| 1 | 港珠澳大桥超高强度平行钢丝斜拉索设计与技术研究显示文摘港珠澳大桥青州航道桥和江海直达船航道桥均采用斜拉桥,斜拉索均采用平行钢丝索。为减小索体阻风面积、减轻重量,在国内首次设计采用1 860MPa钢丝斜拉索。为确保斜拉索技术性能并提高其耐久性,对钢丝关键技术参数进行了研究,对锚具材料及构造尺寸进行了理论计算和设计,并试制成品索开展了物理模型试验。结果表明,钢丝抗拉强度不低于1 860MPa;扭转次数不小于12次;在规定条件下疲劳应力幅达410MPa以上;表面采用锌-5%铝合金镀层防腐性能优;试制成品索的锚固、疲劳及水密性性能均满足规范及设计要求,可应用于港珠澳大桥。 | 刘明虎 薛花娟 | 2014 | 桥梁建设2014，44，5： | 12 |
| 2 | 港珠澳大桥主桥工程中的连续钢箱梁和钢筋混凝土结构显示文摘作为目前世界上最长的跨海公路桥梁工程,港珠澳大桥在设计和施工中遇到了诸多难题,但它们都被一一克服;在此积累的经验非常值得国内外同行借鉴。为此,针对港珠澳大桥主体桥梁工程中连续钢箱梁的施工全过程的温度效应控制、结构性能预测和施工状态控制及钢筋混凝土结构中钢筋锈蚀对结构承载力的影响,本专辑邀请了直接参与到港珠澳大桥建设的科研人员和工程管理人员来分享他们的研究成果和观点,希望能帮助读者了解相关研究工作并促进研究人员开展讨论,以推进该领域的基础研究和技术创新。 | Qiang JING | 2020 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2020，21，4： | 1 |
| 3 | Application of Prefabrication and Assembly to Hong Kong-Zhuhai- Macao Bridge显示文摘The Hong Kong-Zhuhai-Macao Bridge(HZMB)project,which has just been opened to traffic in 2018.The special location,construction conditions,quality requirements and multiple functions of HZMB brought many challenges,such as management,technology,safety and environmental protection.To meet these challenges and ensure the achievement of high quality and 120 years design service life,the HZMB project first introduced the completely new concept of'Large size,Factory production,Standardization and Assembly',which was fundamental to the design and construction.This was developed in consideration of the difficulties of the offshore environment.The core idea was Prefabrication and Assembly,which was to change this HZMB project into onshore work as much as possible by cutting this mega sea-crossing into large sized components,which could be prefabricated on land and then transported to the offshore site for assembly.The success of the HZMB undoubtedly has led the technology of prefabrication and assembly to a new height and recognized scale.This paper describes the implementation process of the concept;'Large size,Factory production,Standardization and Assembly'(LFSA)to the HZMB. | Huaying Lu | 2020 | Frontiers Research of Architecture and Engineering2020，3，2： | 0 |
