摘要
通过对支护结构的受力与稳定性分析,找出影响支护结构稳定的因素,利用多种手段降低地下水位,排出软土层中的自由水,以达到提高有关设计参数取值的目的。结合实际案例分析了深基坑支护设计与施工过程中应注意的问题。为饱和软土地区深基坑支护设计提供了新的设计理念。
Through the supporting structure of the force and stability analysis,found out the factor of the affected the stability of supporting structure,used variour means to reduce the water table,exhausted the free water in the soft soil,to achieve the purpose about improving the design parameters.With the actual case,analsed the design of the deep excavation support and the problem of the construction process.Provides a new concept of the design for the deep foundation ditch in soft-saturated soil areas.
