| 摘 要： | 研究目的:上海和常州的地面沉降观测数据表明在深层抽水时含水层会发生较大的压缩变形,从而导致含水层渗透性的变化,但在现有模型中含水层变形通常被忽略.针对这一问题,本文提出可以考虑抽水过程中含水层渗透性随水位降深发展的实时变化的渗流-变形耦合模型.研究结论:(1)砂性土中孔隙比与渗透系数在半对数坐标中的线性关系；(2)上海...

| Abstract: | Research purposes: The observated data on the ground subsidence in Shanghai and Changzhou demonstrate that the big compression deformation of the pumped aquifers in these two places occurs to cause the permeability change of the aquifer during pumping in deep stratum.However,the current model often ignores the aquifer deformation.In this paper,for solving this problem,a coupled seepage and deformation model based on the actual change of the aquifer permeability with up and down of the water level is offered... |
