多因修建公路引发的工程滑坡问题,然后采用边坡稳定性FLAC/Slope分析软件,对滑坡滑动前、后工况下稳定
性进行数值模拟,并对滑移后的后缘坡体稳定性进行了数值分析。剪应变率云图和稳定性分析结果表明,滑动
后的后缘坡体仍处于不稳定状态,又形成了新的滑坡体。

| Abstract: | Based on analysis of the engineering geology characteristic of No.1 landslide of Taizhou part of the Zhu-
Yong expressway(K120+ 085- K120+ 169), it is pointed out that there are a lot of problems of landsilde due to
the construction of highway along the line. By employing software FLAC/Slope, the stability of the landslide is
analyzed by numerical simulatiion under two states before and after the slidding, and the stability of its rear edge
after slide is also simulated.The results indicate that the rear edge of the landslide after slide is still unstable, and
has formed a new landslide. |
