Underground dam height optimization method for preventing seawater invasion and improving self-purification of aquifer
According to the underground dam height optimization method for preventing and controlling seawater intrusion and improving self-purification of the aquifer, seawater intrusion is prevented and controlled through the underground dam with the height in the optimal interval, invaded seawater can be effectively blocked, the self-purification capacity of the upstream aquifer can be improved, and the problem of underground water pollution of the upstream of the underground dam is avoided. By means of the technical scheme, the underground dam with the height in the optimal interval can effectively block invading seawater and intercept the lower salt water wedge toe area at the position of the dam body, the underground fresh water discharge amount of the upstream aquifer of the dam body can be increased, the self-purification capacity of the aquifer is improved, and the service life of the aquifer is prolonged. Terrestrial pollutants and residual salt water are prevented from gathering at the upstream of the dam body and polluting underground water. According to the designed height optimal interval of the underground dam, the height of the underground dam in the interval is lower than the surface elevation and the 0m contour line. The designed underground dam is low in height, and cost of materials such as cement and steel bars and engineering cost can be reduced.
本发明提供了一种防治海水入侵且提高含水层自净的地下坝高度优化方法,利用高度在最优区间的地下坝防治海水入侵，不仅能有效挡住入侵海水，还能增大上游含水层的自净能力，避免地下坝上游的地下水污染问题。通过本发明的技术方案，高度在最优区间的地下坝，不仅能有效阻挡住入侵的海水，将下咸水楔趾部区域拦截在坝体位置处，还能增大坝体上游含水层的地下淡水排泄量，提高含水层的自净能力，避免陆源污染物和残余咸水在坝体上游聚集、污染地下水。本发明设计的地下坝高度最优区间，区间内的地下坝高度均低于地表高程和0m等高线。本发明设计的地下坝高度较低，能够减少水泥、钢筋等材料和工程花费。
