摘要
湖南省怀化市会同县青朗集镇朗江村中和社区滑坡受地质特征、降雨及人类工程活动等因素影响,近年来经常发生垮塌现象,坡体后缘出现多条拉张裂缝,严重威胁当地人民群众的生命财产安全。在对滑坡地质环境条件、变形特征及影响因素进行分析的基础上,运用传递系数法、采用理正软件对滑坡在不同工况下的稳定性进行评价。结果表明,在暴雨或连续降雨等外力作用下,该滑坡处于欠稳定状态。提出了“裂缝填埋+截排水工程+搬迁避让+挡土墙工程”的防治方案。
Affected by geological features,rainfalls and human engineering activities,landslides in Langjiang Village,Qinglangji Town,Huitong County,Huaihua City,Hunan Province often occurred in recent years,and there were several tension cracks at the back edge of the slope,which seriously threatened the safety of local people′s lives and property.Based on the analysis of geological environment conditions,deformation features and influencing factors of landslides,the stability of landslides under different working conditions was evaluated by the transfer coefficient method and the correction software.The results showed that the landslide is in a less stable state under the action of heavy rains or continuous rainfalls.The paper put forward the prevention and control scheme of"crack filling+interception and drainage project+relocation and avoidance+retaining wall project".
