1、工程建筑论文-东海大桥混凝土结构耐久性策略及高性能混凝土在工程中的应用摘要:上海为了建设全国乃至世界的物流中心和开发海洋自然资源,海洋工程的发展十分迅速。上海深水港的建设已为世人瞩目,对上海经济持续高速发展将起到十分重要的拉动作用。作为上海深水港重要组成之一的东海大桥南起浙江崎岖列岛小洋山岛的深水港区,北至上海南汇芦潮港的海港新城,跨越杭州湾北部海域,全长31公里,是我国较为罕见的大型海洋工程【1】关键词:桥梁混凝土耐久性 一、前言由于东海大桥是连接港区和大陆的集装箱物流输送动脉,对上海深水港的正常运转起到不可或缺的支撑保障作用,因此在国内首次采用100年设计基准期,可谓世纪
2、工程。为保证东海大桥混凝土结构的耐久性,工程采取了以高性能混凝土技术为核心的综合耐久性技术方案。然而我国目前大型海洋工程超长寿命服役的相关技术规范,高性能混凝土的设计、生产、施工技术在工程中的应用方面尚为空白,因此结合东海大桥工程的具体需要,研究跨海大桥混凝土结构耐久性策略和高性能混凝土的应用技术极为迫切和重要。Opinionsandsuggestionsontheparty'smasslineeducationalpracticeAccordingtothecentralandprovincial,municipalunifieddeployment,accordingto
