| 中文摘要:采用正交试验设计和极限平衡方法，以九子崩滑堆积体为实例进行稳定性分析。并对正交试验设计结果进行了极差和方差分析：极差和方差分析结果均显示，堆积体稳定性影响因素敏感性最大的因素为粘聚力c，其次为内摩擦角φ，重度γ对稳定性影响的敏感性较小。找出了影响边坡稳定性的主导因素，为滑坡防治工程提供了参考依据。 |

| Abstract:Taking Jiuzi toppling accumulation as the example, the stability analysis is carried out by using orthogonal experiment design and limit equilibrium method, and the range analysis and the variance analysis are made on the orthogonal experimental design results, all the analysis results show that the most sensitive influence factor of accumulation stability is cohesion c, followed by the friction angle φ, the accumulation weight γ has little effect on the stability. The dominant factors affecting slope stability are found out, which provides a reference for the landslide prevention and control project. |
