摘　　要：布设在岛礁海域复杂波浪环境中的大型多模块浮体的设计及其波浪载荷和安全性评估面临诸多区别于开阔海域中海洋浮体的技术挑战。该文概要叙述近岛礁波浪流演化规律的实测情况、预报岛礁海域波浪环境的"多尺度区域和多尺度网格方法"、近岛礁海域复杂波浪环境中的超大型浮体水弹性力学理论和超大型浮体多模块柔性连接动力学分析方法的部分研究成果。通过模型试验与海上实测数据的对比分析表明,文中建立的理论和数值分析方法对岛礁海域复杂波浪环境中多模块浮体的优化设计和安全性评估的适用性。In the design,as well as wave loads and safety assessments of a large multi-module floating structure deployed near islands and reefs,different from those in the open sea,would inevitably meet great new technical challenges.Briefly described in this paper are part of the solutions to the technical challenges regarding a very large floating structure(VLFS)in such complicated wave environment near islands and reefs.These include the on-site measurements of wave evolution,the“Multi-scale Zone and Multi-scale Grid Technique”of wave environment predictions,the hydroelasticity theory and numerical methods for describing the structural dynamic responses of a VLFS in the area,the dynamic analysis method of multi-module VLFSs with flexible connectors et al.The predictions are compared with the results of the model test results and the on-site measurements.The good agreements approves that the theoretical methods are feasible for optimal design and safety assessment of multi-module floating bodies deployed near islands and reefs.
