深基坑支护工程施工中存在的问题和解决对策

Problems and countermeasures for the construction of deep foundation pit projects

深基坑支护工程施工过程中对坑内的安全要求较高,对坑外土体的稳定性要求也较高,同时还要保证施工过程中附近的建筑物、公路、污水管网、水电煤气等不受损害,不影响其正常运行。深基坑支护工程的难度较大,文章就工程中存在的问题及对策进行论述。

The deep foundation pit construction process has special safety requirements. It requires high sta- bility on the outside of the foundation pit soil. The construction process must ensure the safety of nearby build- ings, roads, sewage pipe network, water, electricity and gas equipments at the same time. Deep foundation pit support engineerings have many difficulties. However, these difficulties can be solved in the proper way. In this paper, the engineering problems and countermeasures are discussed.
