摘　　要：对文献[1]中的主导公式进行了梳理,并在其中增补了可以用来分析具有双层桥面、单室梯形箱梁畸变的几何参数,然后建立了用弹性地基相似梁法分析畸变的计算模型。通过两个示例表明,作这样的调理,不但可以大大节省计算时间,而且还扩大了文献[1]的应用范围。Systematized the guiding formula of rdferance [ 1 ] and added into it the geometry parameters, which may be used to calculate the distortion for trapezoidal box section girder with two storey bridge desking, the computational model of beam on elastic foundations analogy for analysis of distortion is substintuted. It explained by two examples, that adjustment not only greatly economizes the calculational times, but also extends the applying range of rdferance[ 1 ].
