［摘要］基于边坡稳定性分析原理和锚杆支护计算方法，在考虑黄土结构性影响的条件下，分析论证了发生破坏的某黄土工程边坡的失稳原因。通过对边坡的稳定性分析，针对既有建筑给排水管网渗漏形成的土体增湿而造成的黄土工程边坡失稳状况，给出了相应的处理措施。

Impact of pipeline leakage of existing buildings on loess slope stability

Abstract:Based on the slope stability analysis theory and bolting method, the instability reason of a damaging loess slope engineering was analyzed and appraised, in considering the impact of loess structural conditions. The  drainage network leakage of existing building led the humidity of the soil formation to increase. In order to solve the instability conditions of loess slope engineering which was caused by the increasing humidity of the soil formation, the appropriate treatment measures through the slope stability analysis were proposed.

Keywords: unsaturated soil; pipeline leakage; loess slope; slope stability analysis
