摘　　要：结合宁波协和码头改建项目一期工程,介绍20多年前竣工后闲置的一座码头的改扩建设计。对已建结构复核分析后,认为原安全系数法(K值法)与现行极限状态设计方法的安全性水平保持总体相当。结合码头现状,采用系泊分析优化改扩建后的码头平台长度及系缆墩布置。码头上部结构采用无纵梁、变厚度板的布置形式,解决了工作平台工艺荷载区域差异大、布置复杂的难题。并通过油污收集改造解决环保问题。Combined with the first phase of the Ningbo Xiehe wharf reconstruction project,this paper introduces the reconstruction and expansion design of a wharf that was idle after completion more than 20 years ago.After rechecking and analyzing the existing structure,it is believed that the safety level of the original safety factor method(K value method)and the current limit state design method remain the same overall.Combining with the current situation of the wharf,the mooring analysis is used to optimize the length of the reconstructed and expanded quay platform and the mooring piers arrangement.The upper structure of the wharf adopts the layout form of no longitudinal beams and variable thickness plates,which solves the problems of large regional differences in the process load of the working platform and complex layout.And the environmental protection problems are solved through oil pollution collection and transformation.
