摘　　要：箱形截面因其独特的受力特点在桥梁工程中得到广泛的应用,在进行箱梁抗弯设计时剪滞效应分析不可避免。目前剪滞效应的分析方法很多,以某直腹板单箱室简支梁为例,采用不同计算方法,并对计算结果对比分析。Box section has wide applications in bridge engineering due to its special stress characteristics. The analysis of shear lag is inevitable during the bending design of box beam. There are plenty of analysis methods for the shear lag. Taking the single-box simply supported beam of a direct web as an example, the article compares and analyzes the calculation results by the different calculation methods.
