摘要
钢-混凝土组合结构具有良好的力学性能和施工性能,采用组合技术建造桥梁能够产生很高的综合经济效益,近年来国内外的有关研究和工程应用越来越多。本文对钢-混凝土组合桥梁的研究及应用现状进行了简要介绍,其中包括控制混凝土开裂的技术措施、钢管混凝土在桥梁中的应用以及常用组合梁桥的典型构造形式等。最后,介绍了组合桥梁的部分技术创新成果和最新发展趋势。
Composite steel-concrete bridges have high performance in strength, stiffness and ductility, and will lead to advantages in construction and economics. In this paper, the research and practice on composite bridges are briefly introduced, including the technology in limiting the cracking of concrete, the application of concrete filled tubes in bridges and the typical cross-sections of composite bridges. At last. the technical renovation and recent developments on composite hridges are presented.
