| 摘 要： | 滑坡是现代公路、铁路等交通基建工程面临的一个难题。尤其是在重丘、山地等地段修筑公路工程极易出现滑坡地质灾害。这些滑坡的成因以及相关的边坡稳定性分析目前处于半理论、半经验状态。文章基于学堂湾滑坡的地理位置及地质环境条件,从滑坡区地质环境条件、滑坡周界、滑坡体与滑带的物质结构特征、滑床、滑坡变形破坏迹象等,深入分析了学堂湾滑坡的变形特征。在此基础上探讨了滑坡成因,指出大量的雨水和不合理的施工扰动是滑坡发育的外因;坡体本身的地质条件如岩石的裂隙、岩土体的透水性以及水的疏导条件等是其内因。文章将宏观定性分析与定量计算相结合,对滑坡稳定性进行了分析和评价。结合工程实际对滑坡治理措施进行了初步研究,取得了一些满意的效果。

| Abstract: | Based on the geographical seting and geo-environment of Xuetangwan landside,the landside features were analyzed from the aspects of landside range, the material composition of landside-body and slip zone,landside-bed and the deformation-destroyed evidence.Moreover,the formation conditions of Xuetangwan landside were analyzed in depth.At the same time the mechanism of the landside formation was discussed.The stability of the landside was evaluated and the safety factor was given according to qualitative and quantitative analysis.The drainage system and trellis cables,vegetation was adapted to keep the landside mass stability. |
