We conclude that the conjunction intensity between the platform and piles has a prominent impact on the deformation on the surface and there exists the " curtain effect " of the pile that weakens the slide tendency to the sea . it is confirmed the most disadvantageous load cases 通过数值模拟得到以下结论，承台与桩顶连结对码头顶面的侧向位移影响显著；存在桩的“遮帘作用” ，它在一定程度上弱化了岸坡土体向海方向的位移趋势；确定出对码头稳定性最不利的工况荷载组合。
