【摘要】 文中从滑坡地层、滑带(面)及滑床岩土特征、滑坡变形破坏与成因机制等多个方面对该滑坡进行分析。采用室内试验、滑坡滑动前后稳定性分析反算对比等方法综合确定滑动带c、φ值。采用折线形滑面传递系数法计算滑坡稳定系数及剩余下滑力,提出了工程防护措施设计思路及要点。更多还原

【Abstract】 The bedding sliding of new landslide in the process of excavation of a slope is analyzed from the aspects of landslide stratum, sliding zone(surface), rock and soil characteristics of sliding bed, landslide deformation and failure, and genetic mechanism. The values of c and φ of sliding zone are determined comprehensively by laboratory test,back calculation and comparison of stability analysis before and after landslide sliding. The stability coefficient and residual sliding force of landslide are calculated by the method of transfer coefficient of folded sliding surface, and the key points and design of engineering protection measures are put forward.更多还原
