摘要
研究了河北怀来3井的水氡正常年变特征,分析了距井孔40m远的热水井抽水与怀来3井水温、流量的相互关系。结果表明,1995年以后水氡年变化转变为夏高冬低型,其原因主要是受热水井抽水影响。抽水导致流量减小、水温降低和氡值下降;停止抽水后,流量、水温和氡值回升。
The normal yearly variation characteristics of Radon in groundwater from the well No.3 in Huailai,Hebei are studied and correlations between water-pumping of a hot water well,40 m apart from the well No.3,and water temperature and flowing are analyzed.The result shows that yearly variation of Radon in groundwater change into high value in summer and low value in winter,caused mainly by water-pumping of the hot water well.Water-pumping causes water-flowing reduction,lower water temperature and lower Radon value,whereas the water flow,temperature and Radon amount increase after water-pumping stopped.
