摘要
Abstract
In order to solve the canal lining stability against floating problem in high groundwater level of the north Yellow River to North You River of the Middle Route of South-North Water Transfer Project and calculate the groundwater uplift pressure of the canal lining,it reviewed the drainage measures of inner canal slope by using FEM. It analyzed the head sensitivity according to different discharge density,coarse sand cushion layer thickness,filtration coefficient,and foundation soil filtration coefficient combining in stable and unstable infiltration flow conditions. According to the analysis results,it put forward the adjustment measures of drainage blanket and lining tube of different groundwater elevation high level canal for optimizing the design of water supply and drainage and saving the engineering investment.关键词
