改扩建船闸总平面布置的流程分析与应用研究

Research on Process and Application of General Layout of Ship Lock Reconstruction and Expansion Project

针对船闸总平面布置研究多为针对工程实例进行的方案比选、分析或优化,缺少对设计流程系统性研究的现状,结合枢纽上改扩建船闸边界条件复杂、平面布置制约因素多导致总平面方案设计及优化难度大的问题。在梳理、总结已有研究成果和规范要求的基础上,分析了总平面设计的内容、提出了总平面设计的思路、提炼了适用于改扩建船闸工程的总平面设计的关键流程,即闸址分析与设计、轴线分析与设计、引航道布置与设计。最后选取临淮岗复线船闸工程结合提出的设计流程进行总平面布置设计,在引航道布置中提出并复核了折线型引航道布置方案的可行性。

The researches on general layout of ship lock involve mostly in the comparison,analysis or optimization of the strategies covering the engineering practice instead of the design process.In view of the difficulties in the design and optimization of general layout caused by complex boundary conditions and more constraint factors related to ship lock reconstruction and expansion,the existing research results are combined with specification requirements to analyze the detail in general layout design,put forward new idea,and produce key design process applicable to the ship lock reconstruction and expansion,including the analysis and design of ship lock site and axis,as well as the layout and design of approach channel.Finally,the proposed design process is applied in the general layout design of Linhuaigang double-line ship lock project.In addition,the layout of broken-line approach channel is proposed and reviewed.
