摘要
本文以金华市婺城区雅畈镇上岭殿村南侧滑坡为例,介绍了该滑坡的变形特征,分析了该滑坡形成、影响因素。采用地质分析法、稳定性计算和滑程计算,圈定了该滑坡危险区范围,划分了其危害程度。经应急处置手段的时效、施工条件和经济效益等分析对比,采取了前缘反压的处置措施。根据滑坡实时监测数据分析,反压效果较好,滑坡变形明显减缓,为滑坡的勘查、治理和在建重点工程项目赢得时间。
This article takes the landslide in Lingdian Village,Yafan Town,Wucheng District,Jinhua City as an example.The deformation characteristics of the landslide are introduced,and the formation and influencing factors of the landslide are analyzed.The geological analysis method,stability calculation and slip calculation are used to delineate the scope of the landslide dangerous area and divide its hazard degree.After analysis and comparison of the timeliness,construction conditions and economic benefits of emergency treatment methods,the front-edge back pressure treatment measures have been adopted.According to the analysis of the real-time monitoring data of the landslide,the back pressure effect is good,and the deformation of the landslide is obviously slowed down,which will gain time for the landslide survey,treatment and key projects under construction.
