钢筋砼板桥“单板受力”原因分析及处理措施

Reasons and Treatment Measures of Single Beam Bearing of Steel Concrete Plate Bridge

单板受力病害削弱了上部结构的整体作用,降低了桥涵的承载能力,使上部主要承重物件处于非常不利的受力状态,同时给行车安全埋下了严重隐患,故应及时进行处理,而且应在设计阶段就采取有针对性的加强措施,以将此病害消灭在萌芽状态,确保完工后的桥梁正常使用。

The single beam bearing disease weaken the entirety action of superstructure, reduced the carrying capacity of bridge, which made the upper main bearing object in a very unfavorable stress state and planted a serious traffic safety hazards at the same time. So it should be handled timely, and effective reinforcement measures should be taken in design phase so that the disease could be eliminated in the embryonic stage to ensure the normal use after the completion of the bridge.
