全型钢钢便桥设计及施工关键技术研究

STUDY ON THE KEY TECHNOLOGY OF DESIGN AND CONSTRUCTION OF ALL-SHAPED STEEL BRIDGE

钢便桥是一种临时性的桥梁,通常由钢材制成,主要用于在建造中或其他需要跨越空隙的地方提供临时通行。钢便桥通常采用贝雷梁、型钢和钢管的组合进行搭设,当受到场地条件影响和材料限制时,应考虑采用其他钢材进行搭设。本研究以一个全型钢钢便桥为例,对该体系的承载能力、强度、刚度和稳定性等性能进行分析检算,对全型钢钢便桥的可行性给出相应结论。

Steel bridge is a kind of temporary bridge,usually made of steel,mainly used to provide temporary passage during construction or other places that need to cross gaps.The steel bridge is usually constructed by the combination of Beret beam,section steel and steel pipe.When affected by site conditions and material restrictions,other steels should be considered for construction.In this study,the bearing capacity,strength,stiffness and stability of an all-shaped steel bridge are analyzed and calculated,and the feasibility of the all-shaped steel bridge is given.
