Take the road of sustainable development civilengineeringAbstract: Civil Engineering is the oldest in human history "technical science" as a system of industrial activity, the essence of civil engineering production process, is a technical processCivil engineering is the construction of various facilities in science and technology, collectively, both refer to the construction of the object, that is built on the ground, underground, water facilities, a variety of projects, but also refers to the application of materials, equipment and carried out survey and design , construction, maintenance, repair and other technology.As an important basis for discipline, civil engineering has its important attributes: a comprehensive, social, practical, technical and economic and artistic unity. With the progress of human society and development, civil engineering has already evolved into large-scale comprehensive subject, and has many branches, such as: construction, railroad engineering, road engineering, bridge engineering, specialty engineering structures, water supply and drainage projects, port engineering, hydraulic engineering, environmental engineering and other disciplines. There are six professional civil engineering: architecture, urban planning, civil engineering, built environment and equipment engineering, water supply and drainage works and road and bridge projects.Civil engineering is a form of human activity. Human beings pursued it to change the natural environment for their own benefit. Buildings, transportations, facilities, infrastructures are all included in civil engineering.The development of civil engineering has a long history. Our seniors had left a lot of great constructions to us. For example, Zhao Zhou Bridge is the representative of our Chinese civil engineering masterpieces. It has a history of more than 1300 years and is still service at present.Civil engineering has been so rapid development of the period. A lot of new bridges have been constructed, and many greater plans are under discussion. China is a large county. And she is still well developing.However, civil engineers will be facing more complex problems. We should pay attention to the growing population and a lot of deteriorating infrastructures. We should prepare for the possibility of natural disasters. To meet grow needs in thefuture; we should also try to update all the transportation systems.To deal with these problems, we will have to develop innovative and enterprising skills. And we should choose a way that we can go continuously. Hazard Mitigation may be a great choice. Not only can it save money in the long run, but also avoid getting into an embarrassing situation in which we have to rebuild all the broken buildings. And we should also use more environmentally friendly materials when designing or constructing new buildings.Well, to be a brilliant civil engineer is not easy. Today, engineering is a synthetic system. It not only depends on traditional mechanics, but also closely related to advanced science. So Physics, Chemistry, Material Science, Computer Science and perhaps more are all in our civil engineering program.To be a good civil engineer, we should have the ability to apply the knowledge, to design a system, a component, or a procedure of construction. We should also be able to conduct experiments and explain the results. Furthermore, an engineer never works alone, so we shall cooperate with working team, and try our best to communicate effectively.I’m very glad to be a student in this wonderful field. And I will try my best to bea successful civil engineer, to make contributions to our motherland.1 Of civil engineering history, current situation and future development of knowledge1.1.1 Ancient Civil EngineeringAncient Civil Engineering has a very long time span, it is roughly from 5000 BC to the Neolithic Age to the mid-17th century, around about 7000 years. In housing construction, bridge engineering, hydraulic engineering, tower engineering have made brilliant achievements. Some of the masterpieces of ancient civilization handed down a lot, so far stand tall. For example, China's Great Wall, Egyptian pyramids and so on. Built in the 6th century arch bridge, is the world's first open shoulder arch bridge.1.1.2 Modern Civil EngineeringModern civil engineering began in the mid-20th century. Development to date, civil engineering in building materials, structural theory and construction techniques have made very great progress.Building materials, high-strength concrete, high strength low alloy steel,polymers, glass more and more appear in the buildings. Created by world-renowned modern civil engineering construction are: China's Taipei International Financial Center, Shanghai Jin Mao Tower, Kuala Lumpur, Malaysia's oil and building the twin towers, the French Normandy cable-stayed bridge and so on.1.2 pairs of understanding of the status of civil engineeringWith the constant deepening of China's reform and opening up and rapid economic development, China will face a more massive building boom. We can say that we are faced with a leap of civil engineering along with the great development of the national economy a good period. And such a good development environment has been and will continue to be the West's urgent attention.As a cross-century generation, this situation provides us with excellent rare Shizhancaigan unprecedented. At the same time, we feel deeply that this is an "opportunity" and "challenge" coexist, "cooperation" and "competition" intertwined, "innovation" and "follow the old" era of competing, how to create with Chinese characteristics, world-class new era of civil engineering disciplines, a generation of our century's challenges.2. My feelings and understanding: China's Civil Engineering togo the road of sustainable developmentChina's civil engineering has its own particularity.China's coal, oil, gas, water, forests are living in the world total, and per capita, but all below the world average. Population, energy, education, pollution problems have become severe problems faced by the four. Path of sustainable development is imminent. And civil engineering, also will be when a long-term, out of a sustainable development.As a contemporary civil engineer, in the tradition of the brilliant achievements of our predecessors, but also have a lot of the lessons learned have been an accident, in future work to improve innovation and achieve sustainable development.2.1 The rational use of natural resources, focusing on re-use of existing civil engineering infrastructure, to achieve sustainable developmentRational use of natural resources, will have in the civil engineering construction, use and maintenance process, the civil engineer to take the initiative to be saving energy, and maximize the role of both civil engineering facilities.For example, we can take advantage of building green, gray brick walls in the summer, reduce the surface temperature, thereby reducing air conditioning use; can use energy-saving type of brick or insulation composite wall as the wall material, to the role of thermal insulation in winter ; also solar energy, ground heat and other new energy sources, reducing the amount of non-renewable resources to reduce.In addition, the reuse of existing buildings is also an important means of sustainable development. This regard, Shanghai has made a lot of successful experience. This transformation of re-use, consistent with the requirements of modern use, but also save energy, avoid waste, is an effective way.2.2Development and utilization of renewable resources andgreen resources to achieve sustainable developmentChina's annual construction of the building construction waste generated by 4,000 tons, have produced 13.6 million tons of waste concrete, removal processing a large amount of environmental pollution. In addition, China is the world's cement production 20 years of superpower, which in itself is a high consumption of resources, high energy consumption, pollution of the environment industry.Compared with other materials, steel and recycled concrete is more in line with green building standards, this should be to develop the green building materials.In this regard, Japan's Aichi World Expo, give us a vivid lesson: materials, the Expo will be a variety of construction materials on the surface is very high, but many are recycling. Toyota Pavilion wall is made from recycled waste paper processing, long-term venue Japan Pavilion, only the pursuit of harmony between man and nature, but also saves the expenditure, the use of most of the steel and wood, can be recycled. This gave me a number of thought: in the building material selection, the appropriate place in the application of renewable natural resources, save money, but also to achieve a harmonious and sustainable ecological development and architecture, why not?In addition, the World Expo in Aichi Japan Nagakute, Japan Pavilion cocoon-like in order to reduce heat load, the use of green walls, bio-degradable plastic materials and thinning wood (forest wood to be cut fine) to achieve the environmental protection function. "Nature's Wisdom" as the theme of the Aichi World Expo, pavilion building large-scale application of modern scientific and technological achievements, highlighting the environmental and functional, reflecting the natural beauty of the human diligently pursuing. This should also be the future civil engineersto learn and develop.China's building, Professor Li Guohao Yangpu Bridge is also designed classic. Approach part of the spiral structure, saving several hundred million RMB, is a civil and sustainable economic development model.Today, building the world has entered an era of eco-aesthetics, focusing on culture, ecology, engineering and environmental relationship between the human-oriented, energy saving and sustainable development, the focus is the direction of contemporary engineers.3Civil Engineering expertise should have the qualityA good civil engineer, must have the "four elements", that is, knowledge structure, practical skills, ability to structure and the overall quality and innovation. Knowledge structure, including: public basic knowledge, professional knowledge and expertise.We should also note that China's civil engineering industry with world-class level there is a gap. For example, many domestic high-rise buildings (including the Shanghai World Financial Center), almost all of its engineering design borne from abroad, almost all steel products imported from abroad, the general contractor were mostly borne by the foreign countries, only the steel structure fabrication and installation work by domestic unit commitment. Be completely independent intellectual property rights, engineering and construction to achieve the localization, catch up with international standards, we need the young generation to complete!。
