摘要
根据秦巴山区某变质岩边坡的工程地质条件以及边坡与其支护结构体系的变形破坏基本特征等,对边坡的变形破坏机制、滑坡成因作了分析,并证明了该滑坡为变质岩区较典型的双滑面推移式滑坡。通过室内试验分析确定了滑带土的物理力学参数,对该滑坡进行了稳定性评价,根据边坡支护结构体系的变形破坏特征,分析了滑坡支护结构体系选型时应注意支护结构在平面和空间上的合理布置,使结构受力趋于合理。
According to the engineering geological condition of a slope of metamorphic rocks in Qinba Mountain area and the deformation and failure character of the slope and its supporting structure, the deformation and failure mechanism and origin of landslide are analyzed. It is proved that the landslide slided alone two interlaminateal surfaces. The physical and mechanic parameters of slide surface are determined and the stability analysis of landslide is carried out. Based on the deformation and failure character of supporting structure, the supporting structures should be designed reasonably in space.
