Summary:为系统地研究边壁流效应与实验介质特征之间的关系,从与边壁流效应有关系的实验介质出发,选用粗、中、细3种性质的砂粒。基于单组分均介质实验结果分析,设计不同粒径介质的空间组合结构类型,通过物理实验,结合地下水数值模拟技术和数学分析方法,得到渗流实验中不同介质对边壁流效应影响的程度为细砂〉粗砂〉中砂,明确了边壁流效应对地下水渗流和溶质运移的影响。通过实验,为如何预防或减小孔隙介质水文地质试验中的边壁流效应提供参考依据。

In order to make a systematic research on the relationship between the experimental medium characteristics and side-wall effect,the research started from the aspect on the experimental medium which would produce the side-wall effect,and chose coarse sand,medium sand,fine sand. Based on analysis of single-component in homogeneous medium experimental results,the space combination with different sizes medium structure experiments were designed. Through the physical experiment,combined with the groundwater numerical simulation technology and mathematical analysis method,we got seepage experiment in different medium of side wall effect. The degree of obviousness is that： fine sand medium sand coarse sand. It revealed the side wall flow effect,on the in
