摘要：

对国内处于填埋作业状态的某局部滑移堆体边坡开展塘渣反压控制工程实践，监测治理前、后的表面位移、深层水平位移和渗沥液水位，评估滑移治理效果.分析后续填埋作业塘渣反压高度和厚度要求.结果表明：采用塘渣反压后，表面位移速率最大值从130 mm/d降为20 mm/d，填埋堆体单次最大滑移面积从8 994 m2降为1 645 m2，深层最大滑移速率从5.3 mm/d降为0.9 mm/d.分析表明，在实施塘渣反压措施后，堆体现状局部稳定安全系数从1.129提高到1.614.当后续堆体继续堆高时，建议最小反压体高度应高于潜在滑移面的坡脚，最小反压体厚度应保证堆体稳定安全，反压体高度和厚度的最终取值应根据堆体的稳定性和反压工程的经济性进行优化.
Abstract:

The loading berm method was used to control the partial stability of a domestic landfill in a state of work. The surface horizontal displacement, deep lateral displacement and leachate level before and after the treatment were monitored in order to evaluate the effect of the method. The height and thickness of loading berm for subsequent landfill operation was analyzed. The maximum surface slip rate reduced from 130 mm/d to 20 mm/d, the maximum single slip area reduced from 8 994 m2 to 1 645 m2, and the maximum deep slip rate reduced from 5.3 mm/d to 0.9 mm/d. The safety factor of the slope increased from 1.129 to 1.614. When the subsequent height of this waste slope continued to increase, the loading berm should be higher than the toe of potential sliding slope, and the minimum thickness of loading berm is enough to ensure safety. The ultimate height and thickness of loading berm are supposed to optimize according to the safety and economy.
