| 摘 要： | 为评价顺层岩质滑坡的稳定性，分析了影响顺层岩质滑坡稳定性的主要因素,包括地形坡度、坡面走向与岩层走向夹角、地层岩性、岩层倾角以及软弱夹层。在综合分析顺层岩质滑坡统计数据的基础上，建立了基于Logistic回归的顺层岩质滑坡稳定预测模型，并藉此对顺层岩质滑坡稳定性及评价因子进行了定量分析。实例验证表明，该模型预测结果与实际情况基本吻合。

Application of Logistic analysis method in stability prediction of bedding rockslides |
| |
| Abstract: | To evaluate the stability of bedding rockslides, the factors influencing the stability of bedding rockslides such as the landform gradient, the angle between slope strike and stratum strike, stratum lithology, stratum inclination and weak interlayer are analyzed. By comprehensive analysis of the statistics of bedding rockslides, the stability prediction model is established on the basis of Logistic regression. The stability of bedding rockslides is analyzed and the evaluation factors are studied quantitatively. The measured data show that the predicted results agree well with the practical situation. |
