摘　　要：针对目前码头软土地基工后沉降问题突出及相关预测分析不足的情况,以南方某港口驳船码头工后变形监测项目为依托,通过对复杂的边界约束及荷载进行简化,基于二维Biot渗透固结理论和Drucker-Prager(DP)弹塑性本构方程,对某港口码头软土地基工后变形进行有限元计算分析。Aiming at the current outstanding post-construction settlement problem about the wharf soft soil foundation and the shortage of the relevant forecast analysis, we based on one of the post-construction deformation testing projects in southern China to make a FEM analysis about its barges wharf post-construction deformation of the soft soil foundation. After we simplified the complicated boundary constraints and load which based on the Blot seepage under the plane strain consolidation theory and Drucker-Prager（DP） elastoplastic constitutive equation.
