摘　　要：贝雷梁是施工领域常用的一种拼装组合结构,但由于其结构设计和施工上的偏差,往往在其运营阶段出现问题。本文以实桥为研究背景,根据现场实际进行静力荷载试验,对现有结构的承载能力进行评估和判断,并提出了建议,可为现有桥梁的检测和维护工作提供参考。Bailey beam is widely used in the field of construction because of its convenience, rapid erection and strong mobility. However, due to the deviation of structural design and construction, it of- ten has problems in its operation phase. In this paper, the actual bridge is taken as the research background, the static loading test was tested based on the actual situation, the carrying capacity of the existing structure is evaluated and judged, and some suggestions are put forward, which can provide reference for the inspection and maintenance of the existing bridges.
