摘要
某小区的边坡由于连续降雨的原因导致边坡出现局部表土层下滑,对坡脚建筑物和住户存在安全隐患。为此本文采用MIDAS/NX有限元软件进行了数值模拟分析,结果表明:在天然工况下,边坡的稳定性系数为1.005,处于不稳定状态。通过采用支护方案后,边坡的稳定性系数为1.6,位移由之前的35.69mm减小到19.09mm,满足了边坡稳定性要求。验证了MIDAS/NX软件对边坡稳定性分析的可行性与准确性,对今后类似工程有一定的借鉴作用。
A small slope due to continuous rainfall slope leading to local topsoil decline,there are security risks on the slope of buildings and residents.For this reason,MIDAS/NX finite element software is used for numerical simulation analysis.The results show that under natural conditions,the stability coefficient of the slope is 1.005,which is in an unstable state.After adopting the support scheme,the stability coefficient of the slope is 1.6,and the displacement is reduced from 35.69 mm to 19.09 mm,which satisfies the requirement of slope stability.The feasibility and accuracy of MIDAS/NX software for slope stability analysis are verified,which can be used for reference for similar projects in the future.
