摘要

对云南省怒江州泸水一中男生宿舍后山坡滑坡进行勘查,分析了该滑坡的基本特征、形成原因,并用刚体极限平衡法对地震基本烈度Ⅵ度和Ⅶ度两种工况进行了稳定验算。结果显示,该滑坡处于极限稳定状态和蠕动变形状态。针对这种状况,提出了抗滑桩、抗滑挡墙以及削坡减载的治理方案。实践证明,该方案治理效果良好,可供类似工程借鉴。
Through perambulating the landslide on mountainside behind boys' dormitory in the fist middle school of Lushui Nujiang Prefecture Yunnan Province,the basic features and mechanism were analyzed.The stability of the slope in the basic earthquake intensity Ⅵ and Ⅶ working conditions were calucated by means of limit equilibrium method for rigid block.The reasults indicate the slope was in the ultimate limit state and creep deformation state.In response to this,treatment measures including anti-slide pile,restaining wall and slope cutting were raised.It has been found that the remedying has worked well.This paper provide references for similar works.
