将描述半无限域上的一维稳定渗流二维水动力弥散条件下的溶质浓度在空间上变化规律的近似解析解进行适当变换 ,推导出可用于分析相应条件下的室内砂槽弥散试验数据 ,同时估计多孔介质纵向与横向弥散度aL 和aT 的计算公式。最后 ,利用算例说明了数据分析方法的应用步骤。 The approximate analytic solution of the spatial variation of solute concentration in one-dimensional steady seepage two-dimensional hydrodynamic dispersion on a semi-infinite field is described. The analytical data of the sand dispersion in a chamber can be deduced, The formulas for calculating the longitudinal and transverse dispersions aL and aT of porous media are also estimated. Finally, an example is given to illustrate the application of data analysis methods.
