摘要
潮流能作为一种清洁便利的可再生能源,引起了越来越多的关注,但是剧烈的海流作用和复杂的地质条件对潮流能开发提出了严峻的工程技术要求。提出一种钢制潮流能发电平台设计方法,上部框架结构与下部基础嵌岩桩钢套筒整体连接,通过总体预制形成潮流能发电的永久性平台设施,施工期又作为基础嵌岩桩的施工平台。以某工程实例为研究对象,建立整体数值模型,分析了施工期、使用期等工况下的结构内力,并依据相关规范进行设计。结果表明,该平台结构设计满足安全及使用要求,可为近海钢制潮流能发电平台的设计提供一定的参考。
As a clean and convenient renewable energy,tidal energy has attracted more and more attention.However,severe current and complex geological conditions have put forward severe engineering and technical requirements for tidal energy development.A design method for steel tidal energy generation platform was proposed.The upper frame structure is integrally connected with the steel sleeve of the rock-socketed pile of the lower foundation.Through overall prefabrication,a permanent platform facility for tidal energy generation is formed,which is also used as the construction platform of the rock-socketed pile during the construction period.Taking an engineering example as the research object,the overall numerical model was established to analyze the internal force of the structure under the conditions of construction period and service period,and the design and verification were carried out according to the relevant specifications.The results show that the structural design of the platform meets the requirements of safety and use,which can provide some reference for the design of offshore steel tidal energy generation platform.
