我国北方平原地区,农田灌排中涉及的含水层,常常是有越流现象的三层结构含水地层,当处于非开采的天然渗流状态时,第Ⅲ含水层水头高于第Ⅰ含水层水位。进入开采状态后则相反。商丘县李庄乡背河洼地区,属于这种地层结构。研究农田灌溉水资源问题时,对这种地下水的动态特征,应给予足够的重视。本文介绍了应用R—C多层网络模拟研究商丘李庄试区三层结构含水层,越流补给作用的情况.
The aquifers involved in farmland irrigation and drainage in the northern plains of our country are often three-layer aquifers with over-current phenomena. When in the non-exploratory natural seepage condition, the water head of aquifer III is higher than the water level of aquifer Ⅰ. After entering the mining state on the contrary. Liqiu Township, Shangqiu County back River depression, belonged to this stratum structure. When studying the problem of farmland irrigation water resources, sufficient attention should be given to the dynamic characteristics of such groundwater. In this paper, the application of R-C multi-layer network simulation to study the tri-layer aquifer in Li Zhuang test area in Shangqiu is introduced.
