摘　　要： 波形钢腹板箱梁桥应用于宽桥面时,为了保证抗剪,常常需要多道腹板,因而出现单箱多室波形钢腹板组合箱梁桥。然而,在建立单梁模型时,常用软件并不能准确模拟此种截面形式。为此,该文以单箱两室波形钢腹板三跨连续梁桥为例,建立梁格模型与简化的单梁模型进行对比分析,并通过实体模型验证这两种模型的适用性,为该类桥型的设计研究提供参考。 In order to ensure the shear strength,it is often required to use more webs when the steel corrugated web box girder is applied to the wide bridge deck,as the result,there is the steel single-box multi-cell corrugated web combined box girder bridge.However,the common software can not correctly simulate this kind of section shape in the establishment of single girder model.Therefore,taking a steel single-box two-cell corrugated web three-span continuous girder bridge as an example,the article compares and analyzes the built grillage model and the simplified single-girder model,and validates the applicability of these two models by the solid models,which can be referred for the design and study of this bridge shape.
