摘要
麻日滑坡前缘发育3个次级滑体。根据河谷斜坡变形演化机制分析,利用数值模拟及刚体极限平衡计算分析其稳定性,研究结果表明,2#次级滑体发生失稳的可能性较大,但失稳方量小于最小堵江方量,堵江可能性小;另外,对3个次级滑体分别进行涌浪分析和计算,推测涌浪到达坝址的最大涌浪高度。
Three secondary slippers developed at the front edge of the Mari landslide. Based on the analysis of the evolution mechanism of river valley slopes,the stability of the slope is analyzed by numerical simulation and rigid body limit equilibrium calculation. The results show that the probability of occurrence of 2#secondary sliding body is larger,but the amount of instability is less than the minimum and the possibility of catching the river is small. In addition,the wave analysis and calculation of three secondary slides were carried out to predict the maximum wave height of the surge wave to the dam site.
