考虑降雨和地震作用下的铁路边坡稳定性分析
Stability Analysis of Railway Slope under Rainfall and Earthquake
摘要
Abstract
We studied and evaluated the stability of the slope by theoretical calculation and numerical simulation.Firstly,we investigated the surrounding environment of the railway subgrade slope and the causes of landslide in the field,and selected the section with severe slope erosion.The safety factors of the slope under natural,rainfall and earthquake conditions were compared and analyzed by adopting the simplified Bishop method and the numerical simulation method.After that,the stability of the treated slope by the anti-slide pile slope protection,grouted rubble with anchor stock slope protection and retaining wall slope protection were analyzed.Finally,we analyzed the influence of different length and width of anti-slide pile,length and diameter of anchor stock and height and width of retaining wall on slope safety factor and summarized the rule.The results show the subgrade slope can remain stable state after the treatment of three schemes.With the increase of retaining wall height,the slope safety factor increases linearly.When the length of anti-sliding pile increases to 12 m and the length of anchor stock increases to 10 m,the improvement trend of anti-slide ability of slope is no longer obvious.关键词
