禅古村山体斜坡属峡谷区高陡斜坡,地质构造复杂,岩体破碎,“4·14”玉树地震发生后,低位斜坡体坡面岩土体普遍松动,产生了大量的变形裂缝,形成不稳定斜坡。针对禅古村低位山体斜坡稳定性计算,采用不平衡推力法(传递系数法)进行定量评价,参数选区根据实地山坡坡度统计、重度试验、反分析计算等综合选取。
The slope of the Zen ancient village is a high steep slope in the gorge area. The geological structure is complex and the rock mass is broken. After the occurrence of the “4.14” Yushu earthquake, the rock mass generally loosens on the low slope, resulting in a large number of deformation cracks Unstable slope According to the calculation of slope stability of low mountain in Zen ancient village, the unbalanced thrust method (transfer coefficient method) is used to evaluate the stability of the slope. The parameters are selected synthetically based on the slope statistics, severe test and back analysis.
