摘要
防渗墙作为堤防工程的渗控措施对改善堤防的安全状态起到了很好的作用 ,但是沿堤长距离的防渗墙是否对地下水环境产生不利影响是较普遍关注的问题。汛期 ,防渗墙有效防渗护堤 ,枯水季节却阻碍堤内外天然水力联系。该文基于相似性原理 ,以解析法模拟单因素 (长江水位 )影响下的堤防工程对地下水水位的影响 ,解析解模拟值与工程实测值进行对比分析 ,并结合在有。
Cutoff wall, as a seepage control measure, has a good effect on improvement of safety condition of dikes.But whether the cutoff wall has a bad effect on groundwater environment or not has been widely concerned. In flood season, the cutoff wall effectively prevents seepage and protects dikes, while in dry season it blocks the natural hydraulic relation of both sides of dike. This paper simulates the groundwater motion, which is affected by cutoff wall,by use of analytic method,and based on similarity theorem. Combined with the differences of groundwater levels with cutoff wall or not, analytic solutions are compared with measured values and the evaluation of environmental effect is made.
