复杂工况下某边坡稳定性分析

以某管道迁建工程为例，应用Midas/GTS软件模拟分析给水管道施工过程中边坡土体的应力应变规律和边坡稳定情况，确定了给水管道架设的合理方案。结果表明，边坡安全系数随给水管道支墩间距的增大而减小，不同支墩间距，土体应力应变分布差异较大，但支墩间距对挡墙应力影响较小，当考虑雨水渗流作用时，边坡安全系数大幅减低，为其他类似边坡工程提供了有益的参考。

Analysis on Stability of a Slope under Complex Construction Conditions

Taking a pipeline relocation project as an example in Chongqing, researched the Stress and strain regularity and slope stability under the effect of feed water pipe through the Midas/GTS software, determining the reasonable plan of feed water pipe set up. Fruits show that the slope safety factor decreases with increasing of water supply pipe span. It is Significantly different that soil stress and strain distribute in different piers spacing,, but the pier spacing effect on retaining wall stress is small. It provides a useful reference for other similar slope projects.
