九寨沟“8·8”地震后发育大量的土质斜坡崩滑灾害,这一类型的崩滑斜坡坡体较为破碎,厚度较小。传统的传递系数法计算模型应用于这类崩滑斜坡稳定性计算时,存在将边坡整体计算及不能反映局部崩滑稳定性的问题。将崩滑斜坡破碎程度分为:极度破碎、高度破碎、中度破碎、轻度破碎以及不破碎,基于传递系数法,考虑了坡体的5种破碎程度,对滑坡稳定性系数以及推力大小计算模型进行改进。并以九寨沟县热西寨老电站对面崩滑为例,对比了两种计算方法的结果。结果表明:分块差异稳定性计算模型比传统计算方法得出来的数值更符合实际情况,即分块法计算每个滑块稳定性存在差异,有的在极端工况下处于欠稳定,有的处于不稳定状态。基于分块法差异计算结果,得出了崩滑斜坡的分块防治模式。
A large number of soil slope collapses-slides disaster have developed after the “8.8” earthquake in Jiuzhaigou,which is more fragmented and has a smaller thickness. When the traditional transfer coefficient calculation model is applied to stability calculation of such slopes, there is a problem that the overall slope calculation cannot reflect the stability of a slider. In this paper, the fragmented degree of collapse-slide slope is divided into: extreme fragmentation, high fragmentation, moderate fragmentation, slight fragmentation, and no fragmentation. Based on the transfer coefficient method and considering the five degrees of fragmentation of the slope, this paper improves landslide stability coefficient and thrust calculation model. Taking the collapses and slides of old Rexi stockade Power Plant in Jiuzhaigou County as an example, the results of two calculation methods are compared. The results indicate: Compared with the traditional calculation method, the block differential stability calculation model more consistent with the actual situation, so there is a difference in the stability of each slider calculated by this method. Some are not stable under extreme conditions and some are unstable. Based on the difference calculation results of the block method, a block control model for the collapse-slide slope was obtained.
