南水北调中线工程地下水排水数值模拟研究
Study on numerical simulation of groundwater drainage in the middle route of South-to-North Water Transfer Project
摘要
Abstract
Cixian section of the main canal was selected as a case study of the middle route of South-to-North Water Transfer Project ( SNWT), based on groundwater drainage design and exchange between canal water and groundwater. A three-dimensional hydrogeologic architecture model of the study area and a threedimensional numerical model of groundwater flow into the canal with interior drainage were developed to analyze the water exchange under groundwater table fluctuations. Results show that in the design conditions of groundwater discharge and drainage capacity, groundwater drains into the main canal smoothly, ensuring safe operation of the main canal. The major drainage-influencing factors are regional hydrogeologic conditions and dynamic variation of groundwater level. The drainage is closely related to the aquifer where the canal is excavated, and during a year the drainage varies dynamically with phreatic water level.关键词
