摘　　要：支护桩是环梁支护结构体系中的主要组成部分,也是影响基坑支护工程造价的重要因素.它与环梁和压顶梁等共同承受基坑的水、土压力和地面超载等荷载作用.通过一个典型空间分析模型,重点探讨了支护桩直径、桩入土深度以及桩间距等因素对这种支护结构内力、变形性状的影响规律,得出了一些对该种支护结构支护桩设计较有价值的结论.Retaining pile is the main part and important factor of affect cost in Ring beam retaining structures. It is also bearing the loads of water pressure, soil pressure and ground load with ring beam and top beams etc. The retaining pile influences to the behavior of ring beam retaining structure were analyzed by a typical 3-D model, which including the diameter of pile, the embedded depth of pile and the space between piles. The conclusions are valuable in retaining pile design of the retaining structure.
