弥散尺度效应的试验研究进展及展望

Research Progress and Prospects of Dispersion Scale Effect Test

水动力弥散尺度效应问题是地下水中污染物运移研究的重要内容,针对国内外的弥散尺度效应研究,分别从室内和野外两个方面对弥散尺度效应试验研究进行综述。统计了室内试验各影响因素产生弥散尺度效应所占的比例,并根据表格数据分析造成弥散尺度效应的原因。最后,提出弥散尺度效应的试验研究展望:(1)验证弥散尺度效应的存在性;(2)研究弥散尺度效应的产生机理;(3)弥散尺度效应的定量化研究。

The problem of hydrodynamic scale -dependent dispersion is an important aspect of studying groundwater contaminant transport. Aiming at domestic and international study in scale -dependent dispersion, this paper summarized research progress of scale-dependent dispersion from lab and field. The proportion of causing scale-depent dispersion was counted under various influ - ence factors in laboratory test, and the reasons for causing scale-depent dispersion were analyzed according to form data. Finally, study expectation of scale-dependent dispersion were proposed： （1） Testing the existence of scale-dependent dispersion; （2） Studying generation mechanism of scale-dependent dispersion; （3） Quantitative research on scale-dependent dispersion.
