【正文】 Knowledge of civil engineering【Abstract】With the accelerated development of urbanization in recent years, civil engineering bees increasingly important position in economic development.forIn a college students majoring in civil engineering, to have a deep understanding of civil engineering is a must.In this paper, with the historical development of civil engineering and the main content of the civil engineering and the important role, and for the future development prospects of civil engineering on my knowledge of civil engineering.【Keywords】The content of the civil engineering The development direction classification The main content【introduction】around time past the blink, civil engineering professional English course of study is over,Look back the short the four Weeks, through learning this course, I am from Have the professional and industry in the future is in the further Know, at the same time also stimulated interest in civil no matter from which Perspective are very significant. In the future Lesson to learn, We will be right here On the basis of work harder to learn Xi. Below is I through the study of this course in civil engineering A little knowledge.The future development direction of civil engineering1 to the high altitudeNow polish Gabin227kHz artificial highest building is 646 m long steel tower, consists of 15 cordelle root steel plans to build a m high of one thousand in Tokyo tower, it is about miles from the sea, will work, leisure, entertainment, business, shopping and so on into the integration of seismic vertical cities, residents of up to 50000 proposed in Shanghai near km wide, 200 m deep on the island to build a 1250 m of the bionic tower, residents of is also proposed to invested $5 billion to build super skyscrapers, its the earth 202 layers, up to 710 still be visible in the 21st century highrise building is an important development direction of civil engineering.2 to the development of undergroundHeld in Tokyo in 1991 the urban underground space of the international academic conference passed the declaration of the east, proposed the 21st century is the century of human development and utilization of underground space.Construction of underground construction will effectively improve urban congestion, saving energy and reducing noise pollution, in the late 1950 s to 70 s, largescale exploitation and utilization of shallow underground space by the end of the 80 s have started to study 50 ~ 100 m deep underground space development and utilization of the problem.The future urban underground space development mainly has the following trends:(1) is the main trend of foreign underground space development, the first is the emergence of underground plex, bee a symbol of city modernization construction type integrated performance in underground pedestrian system and underground rapid rail system, the bination of highspeed road system, and the bination of underground plex and the underground transport prehensive performance on the ground, underground space function distinguished, and the coordinated development of bination mode.(2) layering and prehensive utilization of underground space resources, underground space development and gradually to the deep such as the United States at the university of Minnesota and mineral engineering of underground building as many as seven layers, vancouver, Canada to build an underground garage up to the 14th floor, with a total area of 72324 m2.(3) the micro tunnel project will speed up tunnel is people can39。t get into tunnel, in 25 30 cm in diameter, and up to 2 the entrance of the tunnel surface is excavation and supporting with the remote method is rapid, accurate, economic and is appropriate under the highrise building,
