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。 Loess area loose soil, earthquakes, loess landslide disaster. In this paper, the landslide stability assessment is analyzed and discussed. Aiming at the deficiency of the traditional two-dimensional stability coefficient calculation method, a three-dimensional landslide stability analysis method is proposed based on the establishment of three-dimensional landslide model, and its feasibility is analyzed Theoretical Analysis and Case Verification. Experimental results show that this method is more accurate, effective and practical than the traditional two-dimensional analysis method.
