某景区滑坡地质灾害分析及治理

摘要

以某景区滑坡地质灾害紧急治理工程为例，通过现场调查、钻孔开挖、标贯测试及稳定性计算，认为上部滑体填土与下部滑床粉质黏土形成结构相对软弱面，受连续性降雨影响土体抗剪强度降低，导致土坡滑动失稳，提出了采用抗滑桩+预应力锚索+截排水+封闭压实土体的综合治理方法，治理效果良好。%In a scenic spot landslide hazard emergency treatment project as an example,through field investigation,drilling and excavation, standard penetration test and stability calculation,the results indicate that the upper sliding body and the lower part of the sliding bed filling silty clay formation structure is relatively weak,due to continuous rainfall soil shear strength reduction,resulting in the slope slide instability,this pa-per used comprehensive treatment method for anti-slide pile + prestressed anchor cable + cut drainage + closed compacted soil,the treatment effect has been great.
