摘　　要：重力式码头或直立式护岸施工中,沉箱吊运安装是一种常见的施工工艺。通过ANSYS有限元软件建立吊孔及起重销三维模型,设置合理的接触对和边界条件,利用其接触分析功能对某直立式护岸工程的沉箱吊孔应力进行分析。得到了吊运过程中吊孔附近的应力分布规律,并提出了吊孔局部受压净面积的计算方法,可为其它类似工程提供参考。Caisson lifting installation is a common construction wharf or upright revetment. This paper builds a 3-D model of hanging technology for the construction of gravity hole and lifting pin by the finite element analysis software ANSYS, sets up reasonable contact pairs and boundary conditions, and carries out a stress analysis of caisson lifting holes of a vertical revetment engineering due to the contact analysis function of ANSYS. The stress distribution in the process of lifting was obtained, and the calculation method of local pressure net area of lifting holes was proposed, which can provide a reference for similar projects.
