图解工程:上海东海大桥关键项目施工照片
点击率:1 资料整理:郭俊飞 来源:公路造价网 发布人:易路教育-冯 时间:2013-5-2
东海大桥起始于上海浦东新区(原南汇区)芦潮港,北与沪芦高速公路相连,南跨杭州湾北部海域,直达浙江嵊泗县小洋山岛。全长32.5公里的东海大桥是上海国际航运中心深水港工程的一个组成部分,被上海市政府列为“一号工程”。
这座大桥的设计者
—— 福建莆田人林元培。
东海大桥(42张)(1936.2 -),男, 我国著名桥梁专家,福建莆田人,出生于上海市。1954年毕业于上海土木工程学校。曾任上海市政工程设计研究院总工程师、中国土木工程学会市政学会副主任。现任上海市政工程设计研究总院资深总工程师。2005年当选为中国工程院院士。2007年荣获何梁何利基金科学与技术成就奖。1989年被建设部命名为首批“中国工程设计大师”。在40多年的桥梁工程设计和桥梁理论研究中,设计或主持设计的大跨度桥梁达20余座,中小桥梁有上百座,涵盖了上海杨浦大桥、卢浦大桥、东海大桥等各种桥型。
他是中共十五大代表。上海市第十届人民代表。四次被评为上海市劳动模范,95年被评为全国先进工作者。由于他在我国建桥技术方面的杰出贡献和突出成就,被授予国家设计大师,荣获1994年度茅以升桥梁大奖。他是上海市南浦大桥、杨浦大桥、徐浦大桥和卢浦大桥以及东海大桥的总设计师。
1993年建成的杨浦大桥,是林元培倾注全部心血贡献于世的最高水平设计成果。在继南浦大桥之后,把世界最新桥型的跨径从465米一下提高到602米,使世界建桥设计水平推到新的高度,这一重大贡献为国际桥梁界所信服和赞叹,为国争得了荣誉。杨浦大桥的胜利建成是他一贯潜心研究,善于总结,勇于实践,敢为天下先的结果。他构思的杨浦大桥塔拉索锚固区构造、箱型钢梁等设计和大跨径斜拉桥整体稳定理论等,均开创了世界先河。他首次提出的第九种跨越能力最大桥型将问鼎于世,引起了国内外桥梁界的关注。
大桥简介
东海大桥工程是上海国际航运中心洋山深水港区一期工程的重要配套工程,为洋山深水港区集装箱陆路集疏运和供水、供电、通讯等需求提供服务。东海大桥全线可分为约2.3公里的陆上段,海堤至大乌龟岛之间约25.5公里的海上段,大乌龟至小洋山岛之间约3.5公里的港桥连接段,总长约为31公里。大桥按双向六车道加紧急停车带的高速公路标准设计,桥宽31.5米,设计车速80公里/小时。
东海大桥工程2002年6月26日正式开工建设,历经35个月的艰苦施工,于2005年5月25日实现结构贯通。大桥宽31.5米,分上、下行双幅桥面,双向6车道,设计时速每小时80公里。大桥全线按高速公路标准设计,设计基准期为100年。大桥的最大主航通孔,离海面净高达40米,相当于10层楼高,可满足万吨级货轮的通航要求。东海大桥在2005年建成通车。159米高的两座大跨度海上斜拉桥主塔在国内最高;位于颗珠山岛和大乌龟岛之间的深海大堤绵延1.22公里,也是国内的突破和创新;而最大的奇迹在于建设速度——在风高浪急的外海,运用高效、科学的施工技术,实现大桥贯通仅用3年!
地位和作用
在上海6000多平方公里的土地上,已经有的桥梁,主要是依黄浦江、苏州河而建,而东海大桥是第一座真正意义上的外海跨海大桥。东海大桥的建成通车,为洋山深水港年内建成开港,加快上海国际航运中心的建设奠定了基础。
东海大桥工程是我国第一座真正意义上的跨海大桥。东海大桥全长约32.5公里,其中陆上段约3.7公里,芦潮港新大堤至大乌龟岛之间的海上段约25.3公里,大乌龟岛至小洋山岛之间的港桥连接段约3.5公里。大桥按双向六车道加紧急停车带的高速公路标准设计,桥宽31.5米,设计车速每小时80公里,设计荷载按集装箱重车密排进行校验,可抗12级台风、七级烈度地震,设计基准期为100年。
东海大桥是上海市跨越杭州湾北部海域通往洋山深水港的跨海长桥,它以"东海长虹"为创意理念,宛如我国东海上一道亮丽的彩虹。大桥色彩是大桥外观形象及展示桥梁个性的直接表现,采用白色、浅灰色作为大桥的主色调,使其与环境和谐统一。目前,世界上在外海已经建成的跨海大桥最长的也只有16公里,而东海大桥建设总长32.5公里,是名副其实的“世界之桥”,也是继杭州湾大桥之后世界第二长跨海大桥。
东海大桥起始于上海浦东新区芦潮港,北与沪芦高速公路相连,南跨杭州湾北部海域,直达浙江嵊泗县小洋山岛。气势恢宏的东海大桥,一头挑起“东海明珠”的洋山岛,一头连接上海南汇的海港新城和物流园区。
结构
2002年6月26日正式开工建设的东海大桥,与海天共一色,是一座以新的理念,新的技术、新的工艺建设的以蓝色为基调的大桥。大桥长32.5公里,陆上段约3.7公里,芦潮港新大堤到大乌龟岛之间跨海段长25.3公里.大乌龟岛至小洋山岛之间的港桥连接段约3.5公里,全桥设5000吨级单孔双向主通航孔一处,通航净高40米。
海天一色的大桥,浓缩科技精华。建设东海大桥缺少现成的海上桥梁施工规范与工艺标准,科技人员经过科技攻关解决了海上大桥的防腐、超大体积混凝土箱梁预制和吊装、全球卫星定位系统定位打桩等一系列难题。
海天一色的大桥,经受安全考验。两座高159米的主塔耸立在海中,呈雄伟的“人”字型。主塔创造了海上大体积混凝土浇注的国内最新纪录,并成功地经受了“蒲公英”、“云娜”两次大台风的袭扰。主塔的支撑192根极长的钢缆如同有力的臂膀,拉起了桥面。
地位
东海大桥位于杭州湾口东北部,舟山群岛西侧,起始于上海浦东的芦潮港,跨越杭州湾北部海域,在浙江省嵊泗县崎岖列岛中大乌龟岛登陆,沿大乌龟山、颗珠山岛至小城子山小洋山港区一期交接点。
意义
东海大桥是上海市跨越杭州湾北部海域通往洋山深水港的跨海长桥,它以“东海长虹”为创意理念,宛如中国东海上一道亮丽的彩虹。大桥色彩是大桥外观形象及展示桥梁个性的直接表现,采用白色、浅灰色作为大桥的主色调,使其与环境和谐统一。目前,世界上在外海已经建成的跨海大桥最长的也只有16公里,而东海大桥建设总长32.5公里,是名副其实的“世界之桥”。
上海东海大桥全长31.7公里。它西起上海南汇区芦潮港东至原浙江省嵊泗列岛小洋山;为上海国际航运运中心洋山深水港专用陆海通道。
全桥集中了我国目前所有建桥最新施工工艺和设备,首次使用全球定位,控制定位;首次进行70\60米整体预应力箱梁预制,,并自行设计制造了海上巨型箱梁预制运输架设安装设备;首次采取预制中\长墩的运输安装施工经验;首次跨海施工。
东海大桥的建成,不但为上海市的发展提供了新的思路,也为我国建设更长\更大的海上通道,积累了丰富的设计\施工\管理经验。
