一种钢结构桥梁抗倾覆锚栓构造

我国近年来钢结构桥梁在公路、市政中小跨径桥梁上的应用越来越多,同时超载重载问题引起的桥梁损害和横向倾覆失稳直至垮塌事故相继发生,已成为桥梁重要破坏形式,总结了近年来国内桥梁倾覆事故,探讨了抗倾覆设计理念,开发出一种桥梁抗倾覆锚栓构造,主要用于中小跨径钢结构桥梁,介绍了其构造特点和应用实例。

An Anti-overturning Anchor Bolt Structure of Steel Structural Bridge

In recent years,the steel structural bridge is used more and more for the highways,and the municipal small-span and middle-span bridges in China.At the same time,the accidents of bridge damage,lateral overturning and instability until collapse caused by the overload and heavy load occur one after another,which have become the important damage forms of bridge.The overturning accidents of bridge in China in recent years are summarized.The anti-overturning design concept is discussed.An anti-overturning anchor bolt structure of bridge has been developed,and is mainly used for the small-span and middle-span steel structural bridges.Its structural characteristics and application examples are introduced.
