以有限元分析法讨论顺层边坡岩层产状与边坡稳定性关系

Discussion on the Relationship between Bedding Occurrence and Slope Stability of Bedding Slope by Finite Element Method

基于景谷高速项目边坡岩层产状特征,以有限元分析法,探讨顺层边坡岩层倾角α与走向夹角β对边坡稳定性的影响。研究发现,中风化砂岩顺层边坡稳定性较好,中风化泥岩顺层边坡稳定性随α的增加而增加,α<30°,β=0时稳定性不佳,α增至40°或β≥30°时,边坡稳定性较好。

Based on the characteristics of slope rock formation in Jinggu high speed project,we discuss the influence of slope angle α and orientation angle β on slope stability by the finite element analysis method. It is found that the stability of the bedding slope of medium weathered sandstone is good,and the stability of the bedding slope of the medium weathered mudstone increases with the increase of α,and the stability is not good when α 30°,and β = 0 is not good. The stability of the slope is better when the α is increased to 40 °or β is more than 30°.
