试谈浅层富水土质滑坡虹吸排水治理建议——以贵州凯里几个滑坡隐患为例
|
摘要
大量事例表明,地下水是造成滑坡不稳定的重要原因,富含地下水浅层土质滑坡的滑体尤其滑带土的力学指标低下,滑体承受的地下水静水压力和动水压力较大,截排水工程成为该类滑坡治理的重要手段,传统的地下排水洞、水平排水孔和集水井抽水等滑坡体排水工程施工难度大、成本高,而"虹吸排水"法对滑坡治理排水,技术简单易行,经济绿色环保,针对富含地下水的浅层土质滑坡滑体,应优选采用地下水"虹吸排水"的治理技术,可望达到尽可能少投资,快速实现滑坡治理的目的。
Many facts prove that groundwater is an important reason for unstable landslide,the mechanics index of shallow ground-rich soil slip mass is low,especially the slip soil,the groundwater hydrostatic pressure and dynamic water pressure for slip mass is big,contained drainage project is an important method for treat this kind of landslide. The traditional underground drainage river,horizontal drain hole,sump pumpling and other slip mass treating projects have the features of big difficulty and high expense,the siphon drainage method is easy to do in technology and green in economy for landslide treatment. For the shallow groundwater-rich soil slip mass,‘siphon drainage method'should be used firstly,so it can treat the landslide quickly with few expense.
