摘要
建立了单一介质承压含水层中定流量同井回灌地下水源热泵抽水和回灌引发的地下水渗流数学模型;利用叠加原理推导了同井回灌地下水源热泵地下水渗流的理论解。通过分析理论解,从中得出稳态降深方程、稳态渗流速度方程、准稳态时间方程和理想井间距方程。定流量同井回灌地下水源热泵引发的地下水渗流能在很短的时间内达到稳态,并且理想井间距仅是含水层厚度和渗透系数比的函数。对于完整型的观测井不论位置如何,其平均降深均为0。
The numerical model of groundwater seepage in unitary homogenous aquifer caused by Groundwater Heat Pump with Pumping ＆ Recharging in the Same Well （GWHPPRSW） with constant groundwater flow was established. The analytic seepage equation of GWHPPRSW was obtained based on principle of superposition. Equations of steady drawdown, seepage velocity, quasi steady time and ideal well distance were obtained through analytic seepage equation. Groundwater seepage caused by GWHPPRSW with constant groundwater flow could reach steady state quickly. The ideal well distance is just the function only of the aquifer thickness and the ratio of permeability coefficient （horizontal/vertical）. The mean drawdown is zero for fully penetrating observation well, wherever the location of the observation well.
