摘 要本论文首先对平阳县五显殿街地区场地的工程地质、水文地质条件进行了详细论述和评价,通过对各种基坑围护结构形式的对比分析,选择混凝土挡土墙为本基坑的支护方案,然后进行详尽的设计,包括对土压力、水压力、支护结构力的计算,并进行稳定性验算(围护桩底地基承载力验算、抗渗验算、抗倾覆验算、整体圆弧滑动验算、板式围护桩强度验算)

Comparing with various retaining and protection structure form of foundation pit,single strut system is chosen as the retaining and protection of foundation pit program
Then,the design is done in the thesis ,including soil pressure,water pressure and calculation of internal force of retaining and protection,verifies the stability of foundation pit(check compatations of foundation bearing capacity at the bottom of surrounding pile,percolation and overturn
