| 摘 要： | 首先简单介绍了呷爬滑坡概况、形成机制和3D-S igm a有限元软件,然后利用3D-S igm a软件对天然条件下呷爬滑坡的稳定性进行数值模拟研究。建立数值计算模型,选取合理的计算参数,计算得出相应的应力场图形,经分析,天然条件下呷爬滑坡存在局部破坏,但整体是稳定的。这为进一步进行蓄水条件下稳定性的有效评价提供了理论依据。 |

| Abstract: | In this paper,general situation of Xiapa landslide is introduced firstly and then its sliding mechanism analyzed.On the basis of the mentioned above,the stability of Xiapa landslide is studied by means of 3D-Sigma numerical simulation under natural situation.Building numerical calculation model and chosening rational calculation parameters,then figures of corresponding stress field are obtained through simulation.Furthermore,calculation production figures are synthetically analyzed,then the stability of landslide under natural situation is evaluated.At present,the results of analysis indicate that although there is local failure in Xiapa landslide,the whole slope is stable.Finally,an essential propose is given to effectively evaluate stability of the landslide under natural impounding conditions. |
| Keywords: | Xiapa landslide mechanism 3D-Sigma stability |
