青藏高原地区某公路滑坡边坡稳定性分析
|
摘要
研究以青藏高原地区某滑坡为例,通过野外地质调查、地质钻探及室内试验等方式,确定了该滑坡形态特征以及分析了其变形破坏机制,并采用传递系数法定量评价了分别在自重、自重+暴雨状态和自重+地震3种工况下的稳定状态,其结果可为该区域及同类滑坡的治理提供科学的理论依据和实际指导。
Based on the Qinghai-Tibet Plateau a landslide as an example,through field geological survey,geological drilling and indoor test,determine the landslide morphological characteristics and analyzes its deformation failure mechanism,and the quantitative evaluation of transfer coefficient method,by self-respect,self-respect and rain,self-respect and earthquake,three kinds of working conditions of steady state,the result for the region and the similar landslide governance provides scientific theoretical basis and practical guidance.
