广东信宜1、2号井水温的同震响应及机理初步探讨

介绍了信宜1、2号井水文地质环境,总结了近年来两井水温的同震响应现象,并对其机理进行了初步的探讨。认为两口井的同震响应虽然形态不一致,但机理是相近的,主要是由于地震波的扰动,随着振动效应的作用,加大了不同含水层间的垂直运动速率,而产生水温上升或下降现象,震后一段时间随着混合通道的闭合或运动速率的恢复,2号井的水温逐渐恢复到原有的水平上。

Preliminary Discussion on Water Temperature Coseismic Response and Mechanism of Xinyi No.1 and No.2 Well,Guangdong

This paper introduces the hydrogeological condition of No.1 and No.2 Well,summarizes the water temperature coseismic response phenomenon of the two wells in recent years,and conducts preliminary discussion on the mechanism.It is concluded that,despite of the different coseismic response forms observed in No.2 Well,the meachanism is similar,i.e.the disturbance of the seismic wave,together with the vibration effect,increases the rate of vertical motion among different aquifers and causes the temperature rise or drop;then after a period following the earthquake,the water temperature of No.2 Well gradually returned to the normal level with the closing of the mixing channel or resumption of the motion rate..
