摘要
针对西南地区软弱地基 ,运用 GEO-SLOPE软件 ,对在斜坡软弱地基上填筑路堤时路堤与地基的应力与变形进行了仿真计算 ,比较了水平软弱地基与倾斜软弱地基路堤填筑的差异 ,并分析了在不同地层坡度、软弱土层厚度及路堤填筑高度下路堤地基的应力与变形响应 ,尤其是下坡脚处等重要部位的关键响应。并结合渝怀线一代表性断面 ,对有无工程措施、各种工程措施的效果等进行了模拟。
Numerical analysis was conducted to simulate the deformation behavior of subgrade embankment on sloped weak ground using commercial software GEO SLOPE.Critical structural responses such as strain and stress at the toe of embankment slope were abstracted to evaluate the effectiveness of engineering measurement used to improve stability potential of the filled embankment.Cross sectional factors influencing the deformation behavior of embankment were also explored. Research results show that numerical simulation can provide reliable and rigorous guide in the design and construction phases in infrastructure development.4 tabs,20 figs,3 refs.
