重庆市肖家包切层岩石滑坡分析与治理

Analysis and Treatment of the Cross-bedding Rock Landslide in Xiaojiabao,Chongqing City

岩层反倾地段,通常坡体稳定性较好,因此公路选线时易对岩层反倾段的切层岩石滑坡忽视或漏判。论文对肖家包切层岩石滑坡的滑坡特征、变形机理、变形监测、稳定性等进行详细分析和论证,并选用最佳方案成功治理了该滑坡,从中得出了宝贵的经验和教训,不仅为切层滑坡认识和设计提供了有力的依据,同时对类似滑坡治理有一定的参考价值。

Because of the better stability of the slope body in the area of adverse-grade terrane, the cross-bedding rock landslides are usually neglected or judged wrongly during selecting the lines of highways. The sliding feature, principle of deformation, monitoring of deformation and stability of shear-layer rockslides occurred in Xiaojiabao were analyzed and demonstrated in details in the paper. Then the best project was adopted to treat the landslide successfully. The valuable experience and lessons not only supplied powerful evidence for understanding the shear-layer rockslides and designing the treatment project, but also provided some reference values for similar landslide＇s treatment.
