摘要
为探索二维弥散参数的确定方法,本研究利用较大规格的渗流槽(340cm×90cm×60cm),以砂卵石为孔隙介质,NaCl 为示踪剂,在室内进行了二维弥散试验.结果表明,该方法是确定纵向弥散度和横向弥散度的可行途径.
In order to explore the method of determining the parameters of two-dimen-sional dispersion,the laboratory test has been done in a large seepage trough(340cm×90cm×60cm)with sand-cobble stone as porous media and sodium chloride as tracer.The result indicates that this method is feasible for determining longitudinal dispersivityand transversal dispersivity.
