| 摘 要： | 小岩头滑坡位于贵州省威宁县二(连浩特)河(口)高速公路K255 010~K255 240里程右侧,属一个大型古滑坡,发育于二叠系上统峨嵋山组玄武岩(P2β)地层中。在高速公路施工中对路堑进行深挖削坡,可能导致古滑坡中部、线路右侧斜坡失稳破坏,发生滑坡。因此,滑坡稳定性评价是重大工程地质问题之一。根据大量勘察试验资料,系统地揭示了滑坡的特征,分析了滑坡形成的控制因素、成因和形成机制,建立了滑坡体稳定性计算模型,利用反演计算法进行稳定性分析与评价,认为两滑体均处于滑动失稳状态。建议对滑坡体进行处理,采用排水、支挡、减压等措施进行整治。

| Abstract: | Xiaoyantou landslides in Weining county of Guizhou province cross the right of estuary Hekou highway in K255 010~K255 240 mileage is a large ancient landslides, which originated basalt-stratum in the upper-Permian period.Highway road constructron is resulted in unstability of slope and sliding,so its evaluation of slidestability is one of the large and important engineering geological project. According to the test, the features of slope are revealed, the controlled factors and causing mechanism of the slope are analysed,thus mathematical model of slidestability is set up. It is considered that two slopes are unstable, and that controlling measures such as drainage works, supporting,decompress are taked. |
