| 摘 要： | 针对某山区沟谷潜水与侧向点源污染水相遇后的混合稀释作用,进行预测评价,建造了物理模型,通过模拟实验研究了污染水输入潜水中的稀释过程及其影响因素。结果表明:污染物质的横向弥散混合作用,因受控于渗流场优势流线的约束,尽管径流延伸很远,污染溶质不会无限制地横向扩散,混合、稀释作用十分有限。

| Abstract: | Based on the seepage sandbox physical model of a groundwater pollution prediction problem for a mountain area,the authors studied the dilution effect of the contaminants in the phreatic water through the simulation experiment.According to the different conductivities,seepage velocities and tracer concentration,the authors carried out 10 experiments,and got 15568 observation data.The results show that the transverse dispersion mixing effect of contaminants is mainly controlled by the advantage streamline in ... |
