| 摘 要： | 为减少地下水源热泵运行对地下空间的影响,运用颗粒迁移理论研究了地下水源热泵长期运行时渗透系数对含水层参数变化特性的影响。结果表明,随着地下水源热泵的长期运行,含水层孔隙率和渗透系数的变化特性与渗透系数的初始值无关,而承压水头的变化特性则受渗透系数的影响,渗透速度为影响含水层参数变化的重要因素之一,较小的渗透速度可有效减少地下水源热泵运行对地下空间的影响。

| Abstract: | The influences of permeability coefficient on variation characteristics of aquifer parameters,under groundwater 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. |
