摘　　要：地下水在渗透介质中的流动是连续的,但却由于补给与排泄条件的变化,地下水的运动处处存在着差异。通过地下水流系统理论形成、发展历史的回顾,简要总结了由沙槽试验获得的地下水在均匀流场中的差异性运动特征。作者对其原因或机制进行了分析,并利用不同直径"类达西试验装置"进行了试验。结果显示,渗透过水断面不同,所获得的渗透系数值不同;且过水断面越大,所测得的渗透系数的值越大。The movement of groundwater in the permeable medium is successive.However,owing to the variation of the supply and drainage conditions,the movement of groundwater in distinct region is different.According to the formation and developing history of the groundwater system theory,this paper briefly described the characteristics of the differential movement of groundwater in uniform flow field obtained from sand tank experiments.This paper analyzed the reasons and mechanisms,and made experiments or tests by using ‘resembling Darcy experiment device＇ with different diameters.The results show that the hydraulic conductivity varies with cross-section of infiltration.The larger the cross section,the greater the hydraulic conductivity.
