摘　　要：安全填埋场边坡开挖后常年裸露,安全系数不满足规范要求,通过对边坡初步的削坡减载,使边坡的稳定性有了一定的提高后,采用注浆微型桩措施,形成群桩阻滑体,同时对周围的岩土体起到提高抗剪强度的作用,经过分析之后安全系数满足要求。另外,增加边坡的坡顶截洪以及坡面排水、坡体排渗措施。从治地表水和治地下水两方面入手,进一步加强了边坡的稳定,达到了加固边坡的目的。Slope of safety landfill site is exposed throughout the entire year after excavation; safety factor is unable to satisfy the requirement of code. Stability of slope will be improved by primary slope cutting for load reduction, grouting micro-pile measures are adopted to form pile group, shear strength of the surrounding rock-soil will be improved, and safety factors can meet the requirement after analysis. In addition, from the aspects of treatment of surface water and underground water, including slope top flood interception,slope surface drainage and seepage drainage, the stability of slope can be strengthened to reach the objective of slope strengthening.
