Abstract
The deep foundation pit of underground sewage treatment plants is prone to instability,sudden mud and water influx in the flow plastic silt layer.Traditional steel support has limitations such as insufficient passive zone soil resistance and excessive support deformation.This study took the flow plastic silt layer foundation pit of a large sewage treatment plant as the object,and solves the safety,stability,and water seepage problems of the foundation pit through the technology of steel and cement wall support.The results showed that the optimized process effectively solved the safety,stability,and water seepage problems of the flow plastic silt layer foundation pit,and controlled the water level fluctuation,support internal force,support structure settlement,and surrounding surface settlement within a reasonable range.关键词
