摘要
利用水化学及同位素水文地质学的方法,对密云水库、潮白河及位于潮白河边的2个地下水分层专门监测井进行取样测试,并结合收集相关资料,从水位、水质及氚、氘、氧-18等同位素方面进行分析研究,对中国古语"井水不犯河水"的水文地质学方面的含义进行了一定的微观层次的分析探讨。得出研究点处潮白河水对50 m外的25 m深的浅井井水有一定的影响,而对67 m深井的影响很小,渗透作用分别滞后约20年和50年。另外三处实例也表现出了这一特点。认为产生这种现象的主要原因是由于粘土类地层的阻水作用以及地层沉积过程中的压实作用,尤其是差异性压实作用会使得水交替非常缓慢。
Using the hydrochemistry and isotope hydrology method,the article gives a preliminary discussion on the Chinese old saying that 'well water doesn't interfere river water' and the influence range of river water in Beijing plain from water level,hydrochemistry,tritium,deuterium and Oxygen-18 and other aspects,basing on collecting relevant data,samplings,analysis and testing to the 2 stratified monitoring wells of Henancun,Miyun Reservoir,and Chaobaihe River.The result shows that the river water has little influence on the 2 wells with the depth of 25m and 67m that about 50m away from the river in the study point,and the permeation effect is about delayed 20 and 50 years.The other 3 cases also reflect the feature.The paper holds the main reason above which is preventing water effect of the clay type strata and the compaction effect during the sedimentary process,especially for the differential subsidence which could cause the water circulation become very slowly.The study has a more important theoretical and practical significance for the construction of riverside water plant,pollution controlling of discharging river and construction of landfill.
