考虑土体固结的桩-土-承台非线性共同作用程序实现

提出了基于固结有限层的考虑土体固结的桩-土-承台非线性共同作用分析方法.在此基础上,介绍了相应的计量程序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PRI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、桩项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.

A Program for the Nonlinear Interaction of Soil- Pile- Raft Considering Soil Consolidation

The analysis method of pile - soil - raft nonilier interaction considering soil consolidation based on the consolidated finite layer method is built in the study. At the same time, the corresponding computing program CPRI developed . The flow charts of main program and pile - soil - raft system subroutine are presented. By the contrast of the contrast of the program PRI and the test of the computing example, the correctness of the program is provde. It can provide the variation of the displacement, pore pressure,counterforce of pile head and the soil counterforce at different time and simulate the whole consolidation procedure by the nonlinear interaction.
