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、无防渗墙情况下地下水波动的差异对环境影响进行评价 Seepage control wall as a dike control infiltration control measures to improve the safety status of dike has played a good role, but the long distance along the dike wall whether adversely affect the groundwater environment is a more general concern. Flood season, impermeable wall impermeable berm, the dry season has hindered the natural hydraulic connections within and outside the embankment. Based on the principle of similarity, this paper simulates the influence of embankment project on the groundwater level under the influence of single factor (Yangtze River water level) by analytic method. The analytical solution is compared with the actual measured value. Differences in groundwater fluctuations under the environmental impact assessment
