广西龙胜县某滑坡稳定性分析与治理研究

根据龙胜县某滑坡勘察、设计资料为基础,结合现场调查,对滑坡地质环境、滑动原因及稳定性进行综合分析。根据现场地貌形态的特征、滑坡变形形态、结构面等分析,推断出滑坡的滑动面,选取三条典型的滑动剖面,计算出滑坡典型断面稳定系数。提出采用预应力锚索、抗滑桩、挡土墙相结合的防治方案,具有较高的实践和理论意义。治理后经监测,滑坡处于稳定状态,表明该滑坡采用综合处治技术完全达到了预期效果,治理效果良好。

Study on Stability Analysis and Treatment of A Landslide in Longsheng County of Guangxi Province

Based on the investigation of a landslide in Longsheng County, the design data and the site investigation, the ge-ological environment, the sliding cause and the stability of the landslide are comprehensively analyzed.According to the characteristics of the site topography, the deformation morphology and the structural plane, the sliding surface of the land-slide is deduced, and the typical sliding section is selected to calculate the stability coefficient of the typical section of the landslide.The control scheme of the combination of prestressed anchor cable, anti slide pile and retaining wall is put for-ward, which has higher practical and theoretical significance.After treatment by monitoring, the landslide is in steady state, showed that the landslide by comprehensive treatment technology of fully achieved the desired effect, the treatment effect is good.
