采用平均固结度通解，将部分渗砂排沙地基转化为等效双层地基；并给出了其一维固结的解析解，进而得到了平均固结度。在此解的基础上，结合现有的解，并结合有限元法，对这些相关程序进行了编码。研究了ρw对固结过程的影响；并以图表的形式给出了相关结果；并对这些解的适用性进行了评价。结果表明，在PTPB或PTIB情况下，用该方法绘制的U - Tv曲线比其他方法绘制的曲线更真实。本文给出的解决方案满足了工程的要求。
The ground by partially penetrated sand drain is turned into an equivalent-double-layered ground with the general solution of average degree of consolidation;and its analytical solution of one-dimensional consolidation is worked out,and furthermore,the average degree of consolidation is gained. Based on this solution,the present existing solutions,and finite element method,these relevant programs are coded. The influence of ρw on the consolidation process is investigated;and the relevant results are prepared in graph forms;and the applicability of all these solutions is evaluated. It is shown that the curves of U - Tv are more actual which is drawn by this solution in comparison with the others in the case of PTPB or PTIB. And the solution given in this paper meets the requirements of project.
