碎石土滑坡综合治理及评价决策方法

碎石土滑坡是一类由降雨激发失稳而产生滑动破坏的滑坡类型,要实现对其综合治理和评价决策,滑坡治理稳定性分析及效果评价就不容忽视.基于官家滑坡实际地质条件和变形破坏情况进行变形破坏机制研究和稳定性影响因素分析,在此基础上实施滑坡工程治理规划处置和治理稳定性分析,然后再参照降雨及滑坡变形情况构建加卸载响应比模型来实现滑坡稳定状态反馈和工程治理效果评价.研究表明:降雨作用及地下水变化是碎石土滑坡变形破坏最主要的动力因素,滑坡工程治理依据排水及抗滑原则确定综合处置措施,经治理稳定性分析,其稳定系数可大幅提高,完全满足不低于1.25的规范要求;并且基于加卸载响应比模型分析滑坡经综合治理后处于安全稳定状态,工程治理措施实施科学合理,工程治理效果显著,综合作用下滑坡稳定性好、安全可靠.
