摘要
钢板桩支护适用于受场地等条件的限制,基坑不能采用放坡开挖,必须进行垂直土方开挖的地下工程施工。分析基坑支护结构土压力的主要影响因素,根据朗肯土压力计算的原理,并通过工程实例,对基坑板桩式支护结构设计中土压力的计算进行完善。
The use of steel sheet-pile retaining structure is restricted by field condition. The step-slope excavation is not suitable for foundation trench and it requires underground engineering construction of vertical earthwork excavation. It analyzes the main influence factors of foundation pit retaining structure earth pressure, and improves the calculation method of earth pressure in pit sheet-pile retaining structure design according to the basic principle of Rankine＇s earth pressure calculation and by means of an engineering project.
