河流阶地与山前冲积扇地段滑坡稳定性分析
|
摘要
针对某高速公路滑坡场地,根据工程地质、水文地质条件、滑坡产生规模、破坏形态等确定其形成机理,在外业地质调查、地质勘探及室内外试验基础上,对滑体稳定状态进行分析,最终确定滑坡最危险圆弧滑动面及其稳定性。由于斜坡结构的复杂性及组成物质的差异性造成斜坡不同的破坏形式,因此选用正确的计算模型、选择有代表性的断面、充分考虑不同的计算工况,对稳定性分析非常关键。
According to the landslide engineering geological,hydrogeological conditions,landslide scale,failure mode,determine its formation mechanism. In field geological survey,geological exploration and indoor and outdoor tests,on the landslide stability analysis,ultimately determine the most dangerous slip surface of landslide and the stability of arc. Due to the differences in the complexity of the slope structure and composition of the substance of the slope caused by different failure form,so the selection of calculation model,choose the right representative section,give full consideration to the calculation of the different working conditions is crucial for the stability analysis.
