| 摘 要： | 为能在初期勘察阶段及少量室内和现场试验的基础上快速、准确地对高速公路边坡进行稳定性评价，提出了一种新的边坡稳定性评价方法。基于福建省高速公路边坡资料，以现场稳定情况为因变量，影响边坡稳定性的14个因子为自变量，利用Logistic逐步回归遴选显著影响因子，建立了边坡稳定性评价的Logistic回归模型。该模型符合拟合优度检验，模型稳定性良好，且预测结果准确。另外，模型影响因子的调查和获取比较容易，模型可处理定性因素，边坡稳定评价过程亦方便、快捷，因而边坡稳定性评价的Logistic回归分析可在高速公路边坡工程中推广应用。

| Abstract: | In order to evaluate expressway slope stability rapidly and accurately based on a small amount of indoor and field tests during initial survey,this paper presents a new slope stability assessment method.Based on slope data from Fujian expressways,field slope stability condition was investigated,and 14 factors that might affect the slope stability were collected;then the Logistic stepwise regression was used to select significant factors,and finally a slope stability evaluation Logistic regression model with... |
