Influence of Permeability Coefficient on Aquifer under Groundwater Source Heat Pump Operation
The influences of permeability coefficient on variation characteristics of aquifer parameters, under ground-water source heat pump long-term operation, are analyzed by particle migration theory in order to reduce the impact of the underground space with groundwater source heat pump operation. The present studies show that the variation characteristics of the porosity and permeability coefficient are not affected by initial permeability coefficient; however, the variation of confined water head is related with initial permeability coefficient; the seepage velocity is an important factor which affects the variation characteristics of aquifer parameters! The smaller value of seepage velocity can reduce effectively the impact of groundwater source heat pump long-term operation on underground space.
