弥散试验是揭示地下水中溶质运移机理和获得弥散系数等重要水质参数的可靠方法之一,也是研究地下水污染物运移必不可少的环节。文中详细介绍了野外弥散试验操作的全过程,求得研究区的弥散参数,所得结果偏大,分析其原因提出风化裂隙的存在,会使得地下水弥散系数明显偏大的新结论,为裂隙地区弥散系数的研究奠定基础。
Dispersion test is one of the reliable methods that can reveal the solute migration mechanism in groundwater and also can obtain the dispersion coefficient and other important water quality parameters.It is an indispensable link in studying groundwater pollutantion migration.This research introduced the whole process of field dispersion test operation in detail,and through the correlation coefficient extremum method,we figured out the groundwater dispersion parameters and it provided an effective basis for the establishment of the groundwater solute transportation modeling.
