【摘要】 简要分析了目前工程上基坑锚杆设计中的滑裂面模式,并从岩土锚杆实际受力状态出发,根据下滑力与抗滑力平衡,较精确地推导了锚杆稳定分析中破裂面倾角形式。与传统的朗肯土压力理论破裂面形式进行了对比,对基坑计算中锚杆的设计计算具有一定的指导意义。更多还原

【Abstract】 The sliding plane mode of soil anchor is briefly analyzed. On the basis of bearing capacity characteristics of the soil anchor and equilibrium of sliding and antisliding forces,the inclination of sliding plane is derived precisely for the stability analysis of foundation pit anchor. Finally,comparison is made of the proposed method and tranditional method used to determine the sliding plane of soil anchor.更多还原
