| 摘 要： | 以川藏公路田妥-怒江段一滑坡为研究背景,采用拟静力法的有限元强度折减法和简化Bishop法对滑坡地震作用下的稳定性进行了计算分析.通过分析得到滑坡整治前在地震作用下处于滑动状态,应及时对该段滑坡进行整治,提出了合理的整治方案并进行了安全性评价.结果表明:整治后滑坡在地震作用下的安全系数大于设计安全系数.研究成果为类似滑...

| Abstract: | The strength reduction FEM method based on the quasi-static method and the simplified Bishop method are selected to analyze the stability of a landslide under earthquake in the background of the landslide of Tiantuo to Nujiang rive section in Sichuan-Tibet Road.The calculation indicates that the landslide under earthquake is in an unstable state and regulation project should be taken in time.Advisable regulation schemes of the landslide are put forward.The results indicate that the safety coefficients after... |
