随着我国经济的发展,大规模的高层建筑地下室、地下商场的建设,大规模的市政建设如大型停车库、地铁、地下变电站、污水处理工程等地下工程的施工都面临深基坑的开挖问题。笔者对基坑开挖的逆作法进行经济技术比较,指出其对工程应用的科学性、合理性;对具体工程提出逆作法施工中的技术难点,逐一给出解决问题的办法。
With the economic development in our country, the construction of large-scale high-rise basements and underground shopping centers, large-scale municipal construction such as large parking lots, construction of subways, underground substations, sewage treatment works and other underground works are all faced with the excavation of deep foundation pit problem. The author compares the economic and technical methods of the excavation of the foundation pit with the reverse method and points out the scientific and rational application of the method to the engineering. The author puts forward the technical difficulties in the construction of the inverted method for the concrete project and gives the methods to solve the problems one by one.
