滑坡体渗流场与库水位波动响应关系研究--以三峡库区李家坡滑坡为例
Research on response relationship between seepage field in landslide and reservoir water level fluctuation:case of Lijiapo landslide in Three Gorges Reservoir area
摘要
Abstract
In view of Lijiapo landslide in Three Gorges Reservoir area, a real-time monitoring system composed of pore water pressure and water content is constructed in the lower part of landslide. Based on the long-term and continuous monitoring data, the variation law of groundwater seepage field in the landslide mass with the reservoir water level fluctuation is studied. The re-sults show that the variation trend of the pore water pressure in the landslide mass is consistent with that of reservoir water level when water level rising, but relatively lags behind and the maximum lagging time is up to 19 h; the variation law of pore water pressure is similar with the rise of water level when the reservoir water level drops, the lagging time is much longer because of groundwater reflow and the maximum lagging time reaches 32 h. The real-time monitoring data and variation curve of water con-tent can well reflect the response law of landslide water content and in the combination with the pore water pressure, the evolution of groundwater seepage field in the landslide can be better analyzed to provide reliable data for numerical simulation and stability evaluation of the landslide.关键词
