| 摘 要： | 位于河北省宽城县某拟建铁路将穿越一老滑坡体,体积约77×104 m3,并在滑坡前缘以路堑方式穿过,因开挖施工导致老滑坡复活.在现场地质调查基础上,阐明了滑坡所在的地质环境条件和发育特征,系统分析了老滑坡的形成原因和复活机理,即老滑坡是受附近断层影响,岩体完整性较差,而前缘河流冲刷和回漩旁蚀降低了边坡的整体稳定性,在暴雨或地震诱发下形成,而修建铁路的路堑开挖则是导致前缘抗滑段失效而复活的主要原因.在现场试验和室内试验成果基础上,分别对沿现滑面和古滑面在不同工况下的稳定性进行计算,并系统分析了铁路路堑边坡开挖对滑坡稳定性的影响程度,并对滑坡治理提出了措施建议. |
| 关 键 词： | 滑坡 复活 稳定性 滑坡治理 |

| Abstract: | In Kuancheng county of Hebei province,a railway to be built will cut across an ancient landslide of about 770 000 cubic meters,and in front of it in cutting way though.Excavation of the cutting slope leads to the ancient landslide revivification.Based on geological survey in the field,this paper expounded the geological environmental conditions and developmental characteristics,analyzed the forming reason and revival mechanism systematically,i.e.: Influence of faults nearby damaged the rock mass integrity,t... |
