| 摘 要： | 基于固结有限层的考虑提出了土体固结的桩-土-承台非线性共同作用分析方法。在此基础上，介绍了相应的计算程序CPRI的实现过程，给出了主程序计算框图和桩土承台支撑体系计算子程序框图。通过程序CPRI检验和算例分析，验证了程序的正确性。程序CPRI可以给出不同时刻桩-土-承台支撑体系的竖向位移、孔压、桩顶反力和土体反力变化的情况，从而模拟了非线性共同作用下固结的全过程。

| Abstract: | Based on the consolidated finite layer theory, the analysis method of the nonlinear interaction on pile group-soil-raft considering soil consolidation is built in the study. And the corresponding computing program CPRI, which simulates the whole consolidation procedure by the nonlinear interaction and provides the variation of the displacement, pore pressure, resultant force of pile head and the soil counterforce at different time, is developed. At the same time, the flow chart of main program and pile-soil-raft system subroutine are presented. Through the test of the computing example compared with the program PRI, the correctness of the program is proved. |
