复杂工况下某边坡稳定性分析

Analysis on Stability of a Slope under Complex Construction Conditions

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。

Taking a pipeline relocation project as an example,the Midas/GTS software is applied to simulate and analyze the stress-strain law of the slope soil body and the stability situation of the slope in the construction process of water supply pipeline,and the reasonable scheme of erecting the water supply pipeline is determined.The results show that the safety factor of slope decreases with the increase of the pier spacing of water supply pipeline.The distributional difference of soil stress and strain is larger if the pier spacing is different.But the influence of pier spacing on the stress of retaining wall is less.When considering the rainwater seepage action,the safety factor of the slope is greatly reduced,which provides the useful reference for the other similar slope projects.
