单板受力病害给桥梁正常运营带来较大的安全隐患,给桥梁上部结构正常结构受力造成严重破坏,直接导致上部结构横向分布不利变化和预制板梁的内力集中,如不及时采取措施,会使桥梁承载能力明显下降和预制板梁产生结构性破坏。文章就单板受力出现的规律、原因及处理措施做出了一定的分析和总结,希望对处理单板受力问题起到一定的借鉴作用。 Single board stress disease brings great potential safety hazard to the normal operation of the bridge, which seriously damages the normal structure of the superstructure of the bridge and directly causes the unfavorable lateral distribution of the superstructure and the concentration of the internal force of the precast concrete slab. If no timely measures are taken , Will significantly reduce the carrying capacity of the bridge and structural failure of precast slab beam. The article makes a certain analysis and conclusion about the regularity, reason and measures of veneer stress, and hopes to provide a reference for dealing with the force problem of veneer.
