摘　　要：大跨度预应力钢筋混凝土刚构连续梁一般情况下采用桥墩和梁体正交形式,当墩梁斜交时,梁体和桥墩受力比较复杂,给计算和设计带来一定难度。论文以某与铁路斜交的刚构连续梁桥为例,介绍了其结构设计的主要参数及建模和加载过程,并通过不同计算模型的比较来验证结构计算的准确性。The large-span prestressed reinforced concrete rigid frame continuous beam generally adopts the orthogonal form of pier and beam body.When pier and beam are oblique,the forces of beam body and pier are more complicated,which brings certain difficulty to calculation and design.Taking a rigid frame continuous beam bridge oblique to railway as an example,this paper introduces the main parameters of its structural design,modeling and loading process,and verifies the accuracy of structural calculation by comparing different calculation models.
