摘要
珠江海心岗大桥主桥采用主跨250m的预应力砼连续刚构,通过近二十年持续对主桥线型监控和质量检测,验证在计算理论、构造设计和理念创新方面的工程应用效果。在交通强国高质量发展的时代背景下,回顾同类型桥梁结构的设计与实践经验,展望未来的发展方向,具有现实的工程借鉴意义。
The main bridge of Pearl River Haixingang Bridge adopts a 250m prestressed concrete continuous rigid frame for main span.Through continuous monitoring and quality inspection of the main bridge for nearly two decades,the application of calculation theory,structural design and concept innovation has been successfully verified.Under the background of high quality development of transportation power,it has good engineering reference significance to review the design and practical experience of the same type structure and look forward to the future development direction.
