| 摘 要： | 黄土地区土质疏松,地震多发,黄土滑坡灾害严重。本文围绕滑坡稳定性评估进行了分析与讨论,针对传统二维稳定系数计算方法存在的不足,在建立三维滑坡模型的基础上,提出了一种三维滑坡稳定性分析方法,并对其可行性进行理论分析与实例验证。实验结果表明,该方法较传统二维分析方法更准确、有效和实用。

| Abstract: | Loess landslide occurrs seriously,especially under the effect of the loess texture and earthquake.Due to the inadequacies of the 2D slope stability calculations,this paper proposed a 3D analysis method in the establishment of an improved 3D loess-slope model.The feasibility of the analysis method was verified by theory and practice.The experimental results showd that 3D calculation method could be not only more accurate and effective,but also more practical. |
