摘　　要：针对支点不在立杆位置,可能造成贝雷梁的破坏问题,建立了贝雷梁的细致有限元模型,分析了支点位置变化对其承载力的影响以及采取加固措施后的结果.研究结果表明:支点位置在立杆处应力偏小,在下弦杆处会产生较大应力,采用加强弦杆或在支点处采用槽钢加强,能有效改善应力.It turns out that if the fulcrum is not in the upright position,the Bailey beam may be destroyed.The detailed finite element model of the Bailey beam was established to analyze the influence of the support position on the bearing capacity and the results of the reinforcement measures.The results show that the stress of the fulcrum at the vertical bar is relatively small,and the stress will be greater at the lower chord.The use of reinforced chords or the use of channel reinforcement at the fulcrum can effectively improve the stress.
