摘要
本文讨论了在兼有传导和垂直对流两种传热作用下,一维稳态温度场所具有的特征和利用钻孔温度测量结果判别地下水对流存在与否及定量评定地下水活动对地温场影响的方法。以新郑矿区热异常区的一热水孔为例进行剖析,检验了方法的有效性。这一实例提供了确定新郑地热异常成因的重要基础。
Vertical ground water movement may significantly influence the geotemperature field. In the measurement of terrestrial heat flow and in the evaluation of geotemperature field for a certain purpose such as evaluation on mine geotemperature field, the effect of ground water movement must be noticed. Therefore, to determine the existance of ground water movement and to evaluate the effect of it on geotemperature field in quantity are significant for the geothermal investigation with above mentioned aim. The characteristics of effect of ground water movement on geotemperature and a method for determining the effect on geotemperature field of ground water by means of temperature profile in boreholes are discussed. The example of No. 911 borehole in Xinzheng is studied in the paper.
