本书作为“长大桥梁建养关键技术丛书”之一,旨在为广大桥梁建设技术人员提供一本可指导城市桥梁设计、施工的技术性参考书。
近年来,随着世界经济快速发展,人们对城市桥梁的美学景观要求越来越高,各种与生态环境、历史文化及美学景观融合的复杂桥型应运而生,越来越多基于新理念、新材料和新体系的城市桥梁不断涌现。相对于公路桥梁,城市桥梁在满足交通功能的基础上,更注重桥梁的景观效果,同时还应兼顾城市历史文化、建筑风格以及桥位周边的规划和环境等因素。欧美、日本等发达国家和地区表现尤为突出,设计师们在新型城市桥梁设计中注重桥梁与环境相协调,融入人性化的设计理念,且根据不同的地形条件,因地制宜,设计出许多造型优美、极具特色的景观桥梁。当前,我国城市桥梁建设日新月异,而天津作为国际现代化大都市,在海河综合开发改造过程中提出了“城市桥梁”概念,并做了大量突破性的尝试。设计师们根据不同的桥位和交通需求,尝试城市桥梁的多样性,融入建筑美学元素,与周边环境相协调,强调以人为本,重视亲水设计,突出行人在桥上行走的体验。
作者多年来一直致力于城市桥梁的设计与施工工作,以本书所述天津海河大沽桥、直沽桥、金阜桥、赤峰桥、富民桥、吉兆桥等6座城市桥梁建设为依托,主持多项、省部级科技攻关项目,获国家科技进步二等奖、天津市科技进步一等奖等奖项,主持设计施工的桥梁获国际桥梁大奖——尤金·菲戈奖、全国优秀工程勘察设计银质奖、中国建设工程鲁班奖、中国土木工程詹天佑奖等奖项。
本书是作者所带领的研究团队多年来理论成果和工程应用的总结,主要面向具有一定工程经验的技术人员,注重创新与实践,力求图文并茂,以实际工程案例的形式方便读者理解和掌握。
本书部分成果来自作者所主持的科研项目,工程设计案例均来自天津城建设计院有限公司主持设计的桥梁,大部分工程施工案例来自天津城建集团及所属公司主持施工的桥梁。天津城建集团及所属公司、天津城建设计院有限公司、同济大学、清华大学、华中科技大学、天津大学等单位为作者的相关研究提供了大力支持,并提出了很多有益的建议,作者对参与本书内容研究的合作者表示衷心的感谢!
当前,我国城市桥梁建设仍处于不断积累和高速发展的阶段,由于时间仓促和作者认识上的局限性,本书疏漏和不当之处在所难免,恳请广大读者不吝赐教,以便再版时修正、提高。
