材料、施工、设计是桥梁发展的三大要素

On Material,Construction and Design,the Three Key Factors for Bridge Development

介绍了混凝土、钢材、钢管混凝土及复合材料在桥梁建造中的应用及发展趋势。简述了桥梁上、下部结构的施工方法及发展方向。阐述了桥梁设计的基本原则、理论体系的完善和设计方法的发展。由此论证了材料、施工和设计是桥梁发展的三大要素。

Firstly, the materials such as concrete,steel products, steel tube concrete and composite material about the bridge construction applications and developing trends were presented in the paper. Secondly, the construction method and developing direction of bridge super and substructures were mentioned. Then, the bridge design was emphasized including its principle, theory system improvement and design method development. As a conclusion, material, construction and design were proved to be the three key factors in the bridge developing.
