地下水源热泵定压差取水方式对含水层渗透性的影响
Influence of constant pressure difference on aquifer permeability induced by groundwater source heat pump pumping
摘要
Abstract
The mathematic model of aquifer particles migration induced by groundwater source heat pump (GWSHP) pumping was theoretically presented. A case which represents the influence of constant pressure difference on aquifer permeability induced by GWSHP pumping was analysed. The results indicate that the hydraulic conductivity increases by 156,16 and 7 times respectively as aquifer porosity increases 2.57,1.86 and 1.59 times respectively of initial value 20,25 and 30 m in five-year operation of GWSHP for different aquifer thicknesses. Considering particles migration, the permeability of aquifer is affected obviously by GWSHP pumping under constant pressure difference.关键词
