山前区云母石英片岩风化层滑坡分析与治理

结合合福铁路某滑坡,从地形、地质特征、地下水、地表降水等特点综合分析该滑坡的形成机理,确立滑坡体的合理滑面、规模,并结合滑坡体特征采用减载、支挡防护及排水治理方案进行综合整治。研究结果:通过施工完成后近1年的变形监测及雨季检验,该滑坡体整体稳定。研究结论:对于山前区云母石英片岩风化层滑坡,应该从地形、地质特征及降水等角度合理确定滑坡体的性质,并采取有针对性的加固措施。

Analysis and Treatment of Weathered Layer Landslide of Mica Quartz Schist in Piedmont Area

In combination with a landslide example at Hefei-Fuzhou Railway,this study comprehensively analyzed the forming mechanism of this landslide from perspectives of topography,geologic feature, groundwater and rainwater,etc. And then the sliding plane and the landslide scale were reasonably determined in this study. Further,combined with the landslide characteristics,this landslide body was treated by using the comprehensive treatment scheme,including load reduction,anti-slide retaining structure,waterproofing and drainage. Through deformation monitoring and rainy season test for nearly one year since the finish of treatment construction,it can be seen that this landslide body after being treated is stable. Finally,this paper come to a conclusion that: as for the weathered layer landslide of mica quartz schist,the nature of the landslide body should be reasonably determined from perspectives such as topography, geologic feature, groundwater and rainfall, etc., and the targeted treatment measures should be employed.
