流量与水温关系的模型研究及地震水温前兆机制的探讨

Model Studies on Relationship between Underflow and Its Temperature and Discussions about Mechanism of Groundwater Temperature Precursor

应力的变化可以导致孔隙水压和渗透率变化,从而引起水流量变化而导致地下水温变化。本文建立了两类热泉的含水层模型和一种自流井模型,讨论了流量与水温之间的定量关系,并对水温前兆的机制包括前兆时间、升降温特点、灵敏度等方面作了初步讨论。

Variations of stress will induce changes in pore pressure and permeability, and subsequent changes in discharge and temperature of underground water. Models of thermal spring and one artesian well are established in this paper. According to these models, quantitative relationship between fluid flow and temperature in a hot spring is certain, and a preliminary discussion is made on mechanisms of water temperature precursors including precursory time, characteristics of temperature rise and fall, and sensitivity, etc.
