The Research on the Properties of 1D-consolidation of Soft Clay Foundation with Upper Hard Crust

基于一维太沙基固结理论,得出瞬时加载条件下双层地基一维固结解析解答,编制了瞬时加载、单面排水的双层地基一维固结计算程序,通过计算程序分析了硬壳层与软土层各固结参数对Us-t以及Up-t的影响规律,对比各种计算双层地基平均固结度的简化方法,结合计算实例说明采用双层地基固结理论计算平均固结度的必要性。

Based on the theory of consolidation of double-layered ground,a solution is given to the problem of one dimensional consolidation considering the instant load and petion drain. The influence of the consolidation parameters of hard crust and soft soil on the consolidation curves is studied by calculating program. By comparison of the various simplified method for calculating the average consolidation degree of double-layered ground in calculating examples,the theory of consolidation of double-layered ground is needed to calculate the average consolidation degree of soft clay foundation with upper hard crust.
