复杂地质条件下基坑支护设计及地下水综合治理

Foundation Pit Support Design and Groundwater Comprehensive Treatment Under Complex Geological Conditions

结合工程实例,对深基坑支护设计进行了研究,分析了基坑渗漏、沉降、变形的原因。通过开展地球物理土层探测工作,探测土层中的地下空洞、地下沉降、地下渗水情况,并增加局部深基坑管井施工以及局部深基坑二次开挖等地下水综合治理措施进行基坑渗漏、地下水处理,取得了良好的应用效果,避免了地下水对基坑的影响,确保结构的顺利施工,积累的经验可为类似工程提供借鉴。

Combined with engineering examples,the supporting design of deep foundation pit is studied,and the causes of foundation pit leakage,settlement and deformation are analyzed.Through geophysical soil layer detection,underground cavities,underground settlements and underground water seepage in the soil layer are detected,and comprehensive groundwater treatment measures such as pipe well construction of local deep foundation pit and secondary excavation of local deep foundation pit are added to deal with foundation pit leakage and groundwater.Good application results are achieved,avoiding the impact of groundwater on the foundation pit and ensuring the smooth construction of the structure.The accumulated experience can be used as reference for similar projects.
