濮阳市引黄灌溉调节水库是一座人工开挖的平原区水库,库区建立在地层结构为粘砂多层结构类型,水库蓄水后存在库岸水平向渗漏问题。为了确定合适的防渗型式,本文应用三维有限元法数值模型对工程防渗布置和运行期的防渗效果进行了模拟计算,重点针对运行工况、防渗墙尺寸和渗透性进行了模拟计算分析,给出了相应工况的工程区地下水位渗流场的变化及优化布置方案。并对拟具体采用的防渗措施进行了分析论证,提出合理的建议措施。
Puyang Yellow River Irrigation Regulation Reservoir is an artificially excavated plain reservoir. The reservoir area is based on multi-layer structure type of viscous sand. After the reservoir is impounded, there is a problem of horizontal leaking of the reservoir banks. In order to determine the appropriate type of seepage control, this paper applies the three-dimensional finite element method to simulate the anti-seepage effect of the seepage control project and the operation period of the project. The calculation of the operation conditions, the size and permeability of the seepage control wall are carried out. Analysis, given the corresponding conditions of the project area of groundwater seepage field changes and optimization of layout. The anti-seepage measures to be adopted are analyzed and proved, and reasonable suggestions and measures are put forward.
