Study on Planning Method of Ocean Space Utilization by Using Structural Systems

通过对本研究人员所属实验室进行的水上商业城、海上休闲码头、深水站和水上机场概念设计过程的分析，提取出概念设计中常见的项目，并将其排列成流程图，在流程图中，项目按照需求分析、创意创造、概念生成、主体设计、分析评价和优化，考虑到主体方案确定是浮式结构体系设计的第一阶段，讨论并提出了浮式结构体系设计到该阶段结束的详细流程图。该详细流程图中包括的重要基本技术如下：（1）环境条件的调查方法，并将其转换为设计输入，特别是大型半潜式平台的波浪和风荷载，（2）关于浮式结构配置、系泊系统和主要材料的选择，制定选择方法，（3）结构构件初始尺寸确定方法的发展，（4）静、动力响应分析方法，结构建模、水动力系数和波浪激振力的确定方法，最后给出了四个浮式结构实例的设计方案，根据建议的流程，将浮动商业城、海上休闲码头、深水站和浮动机场修改为更合理的概念。

Through analyzes of the processes of the conceptual designs of floating business city, marine leisure terminal, deep water station and floating airport, which have been carried out in the laboratory to which the researchers of this study belong, the items commonly required to the conceptual design were extracted and arranged to form a flow diagram.In this diagram, the items are arranged as an order of analysis of needs, creation of idea, generation of concept, principal design, analysis and evaluation and optimization.Considering that the process up to determination of the principal plan is the first stage, the further detailed flow diagram up to the end of this stage of floating structural systems was discussed and proposed. The important elemental technologies included in this detailed flow diagram are as follows : (1) survey methods of environmental conditions and conversion of them into design inputs, especially wave and wind loads for large scale semisubmersibles, (2) regarding selection of floating structural configuration, mooring system and main material, development of the selection method, (3) development of determination method of initial dimension of structural members, (4) regarding static and dynamic response analysis method, determination methods of structural modeling, hydrodynamic coefficients and wave exciting force.Finally, the plans of four examples of floating structures described in the beginning, the floating business city, the marine leisure terminal, the deep water station and the floating airport were modified to more rational concept according to the proposed process.
