摘要
以三峡库区四道桥滑坡为研究对象,在滑坡体上建立了水分含量实时监测系统。通过监测典型降雨过程滑坡体水分含量,对不同钻孔、不同层位水分含量监测仪响应、饱和过程及持续饱和的时间关系进行了研究,从总体上摸清了降雨入渗过程中滑坡体内水分含量动态变化过程。根据实时监测数据结合地层资料、排水设施等可以从整体上解析出滑坡体内降雨入渗的补给、径流、排泄过程。另外,实时监测系统所采集的有效数据及降雨入渗过程分析结果,为建立相关模型并模拟降雨入渗对滑坡体稳定性的影响提供了可靠依据。
It established real-time monitoring system of water content by taking Sidaoqiao landslide in the Three Gorges Reservoir area as an object of study. It studied the different drills,monitoring response of water content at different layers and time relationship between saturation process and sustainable saturation through monitoring the water content of the landslide during typical rainfall process and on the whole to find out the dynamic change process of water content in the landslide during the process of rainfall infiltration. It could generally analyze the whole processes of rainfall infiltration recharge,runoff and drainage of the landslide according to real-time monitoring data and combining with stratum data and drainage facilities. In addition,the analysis results of rainfall infiltration and the effective data collected by real-time monitoring system had provided reliable basis for establishing related numerical models and simulating the influence of rainfall infiltration to the stability of the landslide.
