摘要: 针对万州晒网坝滑坡地质勘查与长期监测滑移趋势不一致的现状,进行滑移机理跟踪,并通过物探验证跟踪结论。研究了135 ~ 175 m 范围变化库水位及24 h 强降水对该滑坡稳定性的影响,揭示了真实滑移面地质状况,纠正了地勘存在的不足,同时分析了滑移破坏机理。结果表明: 该滑坡整体稳定、局部缓慢滑移; 并提出了埋入式抗滑桩、裂隙封闭及地表排水的维护方案。

Abstract: In the light of the inconformity between the geological exploration and long-term monitoring sliding trend of the Shaiwangba in Wanzhou,the sliding failure mechanism was tracked. The tracking conclusions were verified by object diction.The influences of the water level variation between 135m and 175m and the heavy precipitation for 24 hours on the stability of the dam were studied. This study revealed the real geological structure and rectified the problems in geological exploration through physical mechanics detection. The results showed that the whole landslide was stable and the partial slipped slowly and proposed spud for anti-slip,fissure closure and surface drainage.

Key words: engineering geology, landslide tracking, failure mechanism, water level change, soil infiltration, preventive Treatment
