| 摘 要： | 以某公路滑坡为研究对象,在对其影响因素进行分析的基础上,研究其形成机制。建立滑坡地质模型并确定相应的计算方案。经分析,用极限平衡法和强度折减法确定的滑动面位置基本一致;天然状态和饱水状态下的稳定性计算结果也基本一致,天然状态下滑坡稳定,饱水状态下会失稳。采取锚杆支护措施后饱水状态下该滑坡也满足工程设防等级要求。

| Abstract: | On the basis of factors analysis,the formation mechanism of expressway s landslide is studied and its geological model and related calculated schemes are determined. It is found that the critical slip surface of the landslide calculated by limit equilibrium method is almost in accordance with that calculated by strength reduction method,results of stability calculation under the natural or saturated condition are basically the same; the natural slope is in stable situation and the saturated slope is in unst... |
