摘　　要：保证弃土场人工渣土边坡稳定,研究其稳定性及应急治理措施,消除安全隐患,对保障人民生命财产安全具有重要意义。以婺源县某弃土场边坡应急治理工程为例,通过现场调查及灾害预测、理论计算及软件模拟,综合分析边坡稳定性,并提出相适应的边坡应急治理方案。结果显示,通过采取一种以坡顶绿化、雨水导排、坡底固脚为主要措施的应急治理措施后,自然工况、暴雨工况下的边坡稳定性安全系数分别提高了10.8%、36.6%,该应急治理措施既能保证渣土边坡安全,又能防止坡面水土流失,同时还能提升景观效果,对于解决边坡坡体失稳具有明显的实用性,对同类型边坡的分析和治理提供一定参考价值。It is of great significance to ensure the stability of artificial muck slope in spoil ground,study its stability and emergency treatment measures,and eliminate safety hazards to ensure the safety of people's lives and property.Taking the slope emergency treatment project of a spoil ground in Wuyuan county as an example,through field investigation and disaster prediction,theoretical calculation and software simulation,the slope stability is comprehensively analyzed,and the corresponding slope emergency treatment scheme is put forward.The results show that the safety factors of slope stability under natural conditions and rainstorm conditions are increased by 10.8%and 36.6%respectively after adopting an emergency treatment measure with greening at the top of slope,rainwater drainage and foot fixation at the bottom of slope.This emergency treatment measure can not only ensure the safety of muck slope,but also prevent soil erosion on the slope surface,and also improve the landscape effect,which has obvious practicability for solving the instability of slope and provides certain reference value for the analysis and treatment of similar slopes.
