摘　　要：在国内重力式码头结构设计中,受到传统结构分析软件的限制,无法较好地测算码头正常使用极限状态下的水平位移,从而无法评估不均匀水平位移对前沿装卸设备运营的影响,造成“啃轨”等现象,本文采用通用有限元软件PLAXIS 3D对重力式码头进行整体三维空间建模分析,给出测算其不均匀水平位移的分析方法,结合欧洲规范关于码头前沿装卸设备生产运营对水平位移的限值要求,探讨在自动化码头建设中的钢轨安装方法与保障措施,有效解决“啃轨”等质量通病,为港区生产运营期间降本增效提供可靠保障。In the structural design of domestic gravity wharfs,due to the limitations of traditional structural analysis software,it is impossible to better measure the horizontal displacement of the wharf under the normal service limit state,so it is impossible to evaluate the impact of uneven horizontal displacement on the operation of front loading and unloading equipment,resulting in‘rail gnawing’and other phenomena.In this paper,general finite element software PLAXIS 3D is used to conduct overall three-dimensional spatial modeling analysis of the gravity wharf,the analysis method for measuring its uneven horizontal displacement is given.In combination with the limit value requirements for horizontal displacement in the production and operation of wharf apron handling equipment in the European code,the rail installation method and guarantee measures in the construction of automatic wharfs are discussed,which solves the common quality problems such as‘rail gnawing’,and provides a reliable guarantee for cost reduction and efficiency increase during the production and operation of the port area.
