摘　　要：为了分析出改造后的半遮帘式板桩码头的应力状态,结合某码头改造工程,应用ABAQUS建立了有限元二维模型和三维模型,对半遮帘式板桩码头进行受力分析,得出设置半遮帘桩可以大幅减小作用在板桩墙后的土压力,从而减小板桩墙跨中弯矩的结论。在计算过程中发现,应用平行墙理论计算前板桩墙在遮帘桩范围内的土压力时,应将其中静止土压力系数调整为主动土压力系数;计算前板桩墙弯矩时,二维模型和三维模型的计算结果趋势一致,且数值相差很小,在5%以内。To analyze the stress state of the modified wharf structure, combined with a wharf renovation project, the ABAQUS was applied to set up the two-dimensional and three-dimensional FEM. Based on the force analysis of half-covered sheet-pile wharf, it is concluded that the half-covered pile can greatly reduce the soil pressure on the sheet-pile wall, and thus reduce the bending moment in the span. When calculating the soil pressure of front sheet-pile wall in the range of covered pile with the theory of parallel wall, the static soil pressure coefficient should be adjusted to the main soil pressure coefficient. When calculating the bending moment of front sheet-pile wall, the calculation results of two-dimensional model and three-dimensional model have the same trend, and the difference is very small, within 5%.
