摘　　要：咬合桩是具备止水和支护两种功能的基坑支护结构。本文通过工程实例,阐述了咬合桩在含水层地区基坑支护应用中的经验和教训,分析了局部止水失效的原因,提出了咬合桩低强度与桩施工工艺垂直度的改进方法及要求,改进后咬合桩止水起到良好效果,特别是在卵石含水层中,效果显著,对存在含水条件下的深基坑支护工程有借鉴意义。Secant Pile is a supporting structure in foundation pit with sealing and supporting. This paper, through engineering projects, discussed the appliealion of secant pile in foundation pit supporting in the aquifer area, anylised the reasons for the partial seal failure and also proposed the improvement of secant pile in low intensity and vertical pile eonstruetinn technology. The improved secant pile has a good effect on sealing in foundation pit, espeeially in the gravel aquifer, and has referential significance in deep fecundation pit supporting with moisture conditions.
