摘　　要：沉箱式码头在现代港口工程中应用越来越广泛,沉箱形状也越来越复杂。依靠常规的设计方法往往难以确定复杂形状的沉箱结构内力分布。采用大型有限元分析软件ANSYS对摩洛哥Tangier港码头工程的花瓣形沉箱进行有限元分析,得到沉箱在波压力和贮仓压力作用下内力分布规律,可为沉箱设计提供依据。Caisson-wharf is widely used in modern port engineering and the shape of caisson is getting more complex. It is difficult to ascertain the internal force distribution of caisson with complex shape of structure only by routine design method. In this paper, petal-shape caissons at Tangier Port in Morocco are analyzed using ANSYS software. The pattern of internal force distribution under wave and ballast pressure is obtained, which can provide reference for design of similar caisson structures.
