| 摘 要： | 基于Terzaghi-Rendulic理论建立了分级堆载预压耳砂的地基渗流固结的数值模型，用有限单元法（FEM）计算瞬间堆载产生的超静孔隙水压力增量，用有限差分法（FDM）计算孔隙水的非稳定渗流过程，对非均质各向异性的有限深砂地基的超静孔隙水压力消攻和不均匀沉降进行了模拟分析，并就有关问题作了探讨。

| Abstract: | On the basis of Terzaghi Rendulic theory,a numerical model of consolidation was introduced to the sand drained improved foundation under step heaped embankment loading.FEM was applied to calculate the excessive pore pressure rising from instantaneous loading and FDM was applied to simulate the transient flow of porewater.The disappearance of the excessive pore pressure and non homogeneous settlement of the finite deep and sand drained improved foundation were investigated via the numerical simulation.At the same tine some problems were put forward for further research. |
