中国桥梁工程学术研究综述·2014

Review on China's Bridge Engineering Research:2014

为了促进中国桥梁工程学科的发展,系统梳理了各国桥梁工程领域(包括高性能材料、桥梁作用及分析、桥梁设计理论、钢桥及组合结构桥梁、桥梁防灾减灾、桥梁基础工程、桥梁监测、评估及加固等)的学术研究现状、热点前沿、存在问题、具体对策及发展前景。首先在总结了中国桥梁工程建设成就的同时对未来桥梁工程的发展趋势进行了展望;然后分别对上述桥梁工程领域各方面的内容进行了细化和疏理:高性能材料方面重点分析了超高性能混凝土(UHPC)和CFRP材料,桥梁作用方面分析了车辆荷载和温度,钢桥及组合结构桥梁方面分析了钢桥抗疲劳设计与维护技术和钢-混凝土组合桥梁,桥梁防灾减灾方面分析了抗震、抗风、抗火、抗爆和船撞及多场、多灾害耦合;最后对无缝桥、桥面铺装、斜拉桥施工过程力学特性及施工控制、计算机技术对桥梁工程的冲击进行了剖析,以期对桥梁工程学科的学术研究提供新的视角和基础资料。

In order to promote the development of China＇s bridge engineering subject, the academic research status, hot issues, existing problems, correspondent countermeasures and development prospects about bridge engineering at home and abroad （including high performance materials, function of bridge and its analysis, bridge design theories, steel and composite structure bridges, bridge disaster prevention and mitigation, bridge foundation, and bridge monitoring, evaluation and reinforcement） were studied systematically. Firstly, China＇s bridge engineering construction achievements were summarized and the development trend of bridge engineering in the future was introduced. Secondly, all aspects of the field in bridge engineering were analyzed in detail： ultra high performance concrete （UHPC） and CFRP materials in high performance materials~ vehicle load and temperature in bridge function; anti-fatigue design of steel bridge, its maintenance technology and steel-concrete composite bridges in steel and composite bridges; and seismic performance, wind resistance, fire resistance, anti-explosion, collision and more than one disasters, multi-disaster coupling in bridge disaster prevention and mitigation. Finally, the mechanical characteristics and construction control in the jointless bridges, bridge decks, cable-stayed bridges during construction and the impact of computer technology on bridge engineering were analyzed. This paper is supposed to provide new perspectives and basic data for academic researches on bridge engineering subject.
