| 摘 要： | 四川省宣汉县天台乡特大型滑坡通过综合治理,滑坡整体稳定性已得到保证,但抗滑桩前的坡体在暴雨天气下,发生了局部垮塌,对滑坡整体稳定性产生不利影响。在对四川省宣汉县天台乡滑坡桩前不稳定斜坡的整体稳定性分析的基础上,本文采用极限平衡法对局部不稳定斜坡作出了评价,并根据分析结果,提出了以抗滑支挡、削坡减载和地表排水相结合的治理措施。

| Abstract: | The stability of Tiantai Landslide in Xuanhan county,Sichuan province has been controlled by comprehensive engineering treatment.The slope in front of the pile collapse partly in the case of heavy rainfalls.On the base of analysis on the stability of the whole unstable slope in front of the pile of Tiantai Landslide,this paper makes an evaluation of stability in part of the unstable slope by limit equilibrium method.According to the analysis mentioned above,this article put forward the dealing approach combined with retaining structure,cutting slope and unloading and surface drainage. |
