Study on Civil Engineering with the Comparison and Inspiration of Domestic and Foreign City Underground Space Development

摘要

With the development of city, city population, regional planning and city ecological environment are facing with more and more tremendous pressure, so the development and utilization of city underground space has become common concern. In recent years, underground structures have been widely applied in the fields of city construction, transportation, defense engineering, water conservancy project etc. Many countries in the world have been the development and utilization of underground space as an important way to intensively implement the land resource and sustainable development of the city. In our country, there is still very great potential of underground space development and utilization of underground structure. Human development and utilization of underground space has long history. In our country, storage of food in the underground has a history of over 5000 years. During World War II, the combatant country's ground factories and buildings were destroyed greatly but the underground factories, warehouses, military facilities constructed in the tunnel, karsts caves and mines were all safely and soundly. Since the 70's, with the development of modern science and technology and industry, the utilization of underground space gradually shifted to protect the environment, save energy, to solve the city traffic.
