摘　　要：通过对福建沿海地区地质状况的分析 ,提出了新型的排桩 -环梁 -锚杆联合支护体系。通过在几个工程中的成功应用和实测成果 ,证明该支护体系能较好地解决福建沿海特殊地层条件下的深基坑支护问题。对这种支护体系设计中排桩的计算分析、环梁支撑系统计算、锚拉结构与环梁支撑的协调以及水压力计算等问题进行了讨论。After successful application in some engineering examples,the supporting system combined with piles,ring beam and anchor has been proved to be effective in solving supporting problems of deep excavations of coastal special geologic conditions in Fujian province.This paper discussed some problems in the design of this kind of supporting system,such as calculation analysis of piles and ring beam supporting system,anchor assorting with ring beam supporting and hydraulic pressure in soil,etc.
