摘　　要：以三亚大东海经济适用房基坑支护工程为实例,研究了超前桩复合土钉墙的稳定性。依据圆弧滑动分析法的原理,采用MATLAB软件进行编程,分别对各种可能的土钉和超前桩破坏方式进行了分析,计算出各工况下基坑的最小稳定系数。最后分析了超前桩复合土钉墙支护结构中超前桩对基坑稳定性的影响,为超前桩复合土钉墙的设计提供依据。Taking foundation pit support engineering of Sanya Dadonghai economically affordable housing for example, this paper studies the stability of composite soil nailed wall with advance piles. According to the principle of arc slip analysis, and by adoption of MATLAB soft programme to analysize respectively the various possible destruction of soil nailed and advance pile, it calculates the minimum stabilizing factor of foundation pit under each working condition. In the end, it also analyzes the influence of advance pile on foundation pit stability in support structure of composite soil nailed wall with advance piles.
