摘　　要：采用梁格法分析小箱梁桥时,为了简便准确的模拟虚拟横梁刚度,根据小箱梁桥的横向构造提出一种分段式模拟虚拟横梁的方法,并以一跨30 m简支小箱梁桥为例,通过与板单元模型计算结果对比,验证了这种方法的有效性和准确性。In order to simulate virtual beam rigidity of small box girder bridge simplely and accurately by grillage method, according to the transverse structure of small box girder bridge, which is put forward a method of virtual beam sectional simulation. In a span of 30 m small box girder bridge as an example, through compared with the results plate element model, validate the validity and accuracy of the simulation method.
