摘　　要：针对综合码头管线品种和数量增多,管线敷设难度增大的问题,提出一种新型的管沟结构设计,能方便多管线的敷设和维护,满足管线布置及人员通行要求。通过在传统上横梁前沿和后沿局部开设孔洞,搁置管沟纵梁,形成一个贯穿于码头面以下的空间体系,释放高桩梁板码头双层使用功能。采用Midas Civil计算软件三维实体单元建模,对内力进行计算和分析,结果表明:横梁结构内力满足规范要求;并将码头结构水平横向分配系数与规范分配系数进行比对,数据基本一致,确保了排架水平力横向分配的安全性和合理性。该结构设计可为同类型码头提供借鉴与参考。Regarding the increasing variety and quantity of pipelines at the comprehensive wharf and the growing difficulty in pipeline laying,a new type of trench structure design is proposed.This design facilitates the laying and maintenance of multiple pipelines,while meeting the requirements for pipeline layout and personnel access.By introducing holes at the front and rear edges of the traditional transverse beams and laying longitudinal beams in the trench,a spatial system is formed that runs below the wharf surface,allowing for the utilization of the double-deck function of the high-pile beam slab wharf.The three-dimensional solid element modeling using Midas Civil calculation software is employed to calculate and analyze internal forces.The results show that the internal forces in the transverse beam structure meet the standard requirements.Additionally,a comparison between the horizontal distribution coefficient of the wharf structure and the standard distribution coefficient shows that the data is basically consistent,ensuring the rationality and safety of the lateral force distribution of the support frame.This structural design can serve as a reference for similar types of wharves.
