| 摘 要： | 在1998年之后,长江堤防部分堤段采用了垂直防渗墙措施来处理堤身和堤基中存在的渗流隐患问题,但与此同时,也有人担心防渗墙实施后,会影响原有的江水与地下水之间补给排泄关系而带来新的环境问题.本文将以某实施了防渗墙的堤段为例,采用GMS软件中的MODFLOW计算模块模拟分析临江地层中地下水与江水的动态互动关系,并重点讨论了防渗墙实施后对这种关系的影响,分析结果认为,防渗墙实施后一般不会带来新的地下水环境问题.

| Abstract: | The hidden trouble and seepage problem in dikes of the Yangtze River and their foundations have been dealing with by constructing vertical cutoff wall since 1998. But there is a worry about groundwater environment due to the change of water exchange between the river and groundwater due to cutoff wall in the alluvium. the dynamic process of groundwater movement in a dike has been simulated by using the MODFLOW module of GMS (Groundwater Modeling System). Especially, the effect of cut-off wall on the groundwater table in the aquifer has been discussed emphatically. The results of numerical analysis show that it is impossible that the cut-off wall in dikes would bring about new problem of water environment. |
