| 摘 要： | 为了确定堤防工程双层地基渗流模型区域在满足渗流分析精度下的截取范围 ,从堤防工程双层地基渗流理论解出发推导出模型截取范围 (L)与渗流量计算误差 (p)之间的关系式 ,并据此求出了能满足工程应用的渗流分析精度时的模型截取范围。将这一范围称为有效长度 ,其值为 3/A。

| Abstract: | In order to determine the cutting out range of seepage model which must meet precise requirements of seepage analysis for two stratified foundation in the levee engineering,a relation expression between length( L ) representing the model cutting out range and computed error ( p ) of seepage discharge is derived on the basis of seepage theoretical solution for two stratified foundation in the levee engineering,and, by this formula,a model cutting out range which can satisfy seepage analysis precision for engineering application may be determined.The effective length( L e ) of model is equal to 3/ A . |
