【摘要】 从井水温动态影响因素、井水温对动力加载的响应机理、水-热动力学理论模型三方面阐述了井水温研究进展。高精度数字化观测技术,为井水温的科学研究提供可靠、有效的数据支持。补给源和水动力作用是影响井水温动态变化的两大因素,补给源决定了井-含水层系统温度的垂直分布曲线的形态,水动力作用决定了含水层地下水补给量的多少和地下水流速的快慢,从而影响井-含水层系统温度变化的大小,而动力加载作用影响井-含水层系统内部的水流流动速度,改变水温变化情况。通过对井水温动态影响因素与水-热动力学形成机理研究的总结,有助于厘清井水温动态和含水层的关系,为井水温动态的定量分析和机理解释提供重要的研究思路。更多还原

【Abstract】 This paper describes the development of water temperature research from three aspects—influence factors, response mechanism of water temperature to dynamic loading and hydro-thermodynamic theoretical model. High-precision digital observation technology provides reliable and effective data support for the scientific research of well water temperature. Source of replenishment and hydrodynamic action are two major factors that affect the dynamic change of well water temperature. The source of replenishment determines the shape of the vertical distribution curve of the temperature of the well and aquifer system. Hydrodynamic action determines the amount of groundwater recharge and the speed of groundwater flow in the aquifer, thus affecting the temperature change of the well-aquifer system. And the dynamic loading affects the flow speed of water within the well-aquifer system and changes the water temperature. Through the summary of the study on the factors influencing the water temperature of the well and the formation mechanism of water-thermal dynamics, it is helpful to clarify the relationship between the water temperature of the well and the aquifer, and provides an important research method for the quantitative analysis and mechanism interpretation of the water temperature of the well.更多还原
