席家院子滑坡形成机理与稳定性评价OA
Formation Mechanism and Stability Evaluation of Xijiayuanzi Landslide
席家院子滑坡位于四川省广安市华蓥市，为一“浅层土质牵引式滑坡总方量约5.5×104m3，该滑坡主要威胁对象为滑坡体前缘的28户112人的生命安全及基础水利、电力设施和公路安全，威胁资产约500万元。本文在充分收集相关资料的基础上，论述了滑坡区的工程地质特征，研究了滑坡的发育特征和形成条件，分析了滑坡的演化机理及变形破坏特征。通过经验、试验及反演计算综合确定了滑坡岩土体物理力学参数，并采用极限平衡法对滑坡在自然工况、暴雨工况、地震工况等3种不同工况…查看全部>>
Xijiayuanzi landslide, located in Huaying County of Guangan City of Sichuan Province, is a retrogressive landslide with shallow soil property. The total volume of the landslide mass is approximately 5.5×104 m3. The below area of landslide includes a settlement with 112 persons, and road, electric power, water conservancy facilities. The potential economic losses are about 5 million yuan. Based on the data collected, the engineering geologic characteristics, …查看全部>>
