pumping rate

According to the related theories of groundwater hydrodynamics,a conceptual geologic model of the thermal energy storage well is established,and the calculation expression of the pumping rate is deduced.

根据地下水动力学相关理论,建立了热储井的地质概念模型,确定了井涌量的计算公式;从回灌水温对渗透系数和贮能井开采量产生影响的角度出发,比较了不同水温下的水源井抽水量随水位降深的变化以及水源井热影响半径随抽水量的变化,分析了回灌水温变化对抽水量的影响,其结论可为实际应用提供参考。

Derived from the most outstanding characteristic of the effects which the grouting pressure has on grout diffusibility, this article poses a method, that suggests grouting and pumping are simultaneously applied, this method will be helpful to increase the grouting hydraulic gradient as well as expand the effective grout diffusivity rad.

本文从注浆压力对浆液扩散影响最显著的特点出发，提出用注浆孔与抽水孔同时工作的方法，这种方法可使浆液水力坡度增大，增加浆液有效扩散半径，提高深表土层注浆效果。
