在土中渗流遵从Hansbo非达西渗流的前提下,考虑实际工程中的变荷载,利用解析与数值相结合的半解析方法,对成层地基一维固结问题进行数值求解。将基于Hansbo非达西渗流的双层地基一维固结半解析解与相应的差分数值解进行对比,验证了半解析方法计算基于Hansbo非达西渗流下成层地基一维固结问题的可靠性。最后,对某三层地基考虑Hansbo非达西渗流的一维固结实例进行计算分析,结果表明:基于Hansbo非达西渗流下成层地基的沉降发展速率与超孔隙水压力的消散速率是不一致的。
Under the condition that the seepage in soil follows the non-Darcy flow of Hansbo, the one-dimensional consolidation problem of layered soils is solved numerically by using the semi-analytical method combining the analytical and numerical methods. Comparing the one-dimensional consolidation semi-analytical solution of two-layer foundation with Hansfeld non-Darcy flow with the corresponding differential numerical solution, it is verified that the semi-analytical method can be used to calculate the reliability of one-dimensional consolidation based on Hansbo non-Darcy seepage flow Sex. Finally, a one-dimensional consolidation example considering the non-Darcy flow of Hansbo in a three-layer foundation is calculated and analyzed. The results show that the sedimentation rate and the dissipation rate of excess pore water pressure are not consistent based on the Hansbo non-Darcy seepage flow of.
