摘　　要：通过利用桥梁博士对变截面连续箱梁的结构计算,阐述了单箱双室截面、斜腹板的变截面连续箱梁(箱梁截面变化复杂,顶板、底板、腹板厚度,梁高均为变化值,且梁底呈二次抛物曲线变化)的建模过程。阐明若采用普通方法输入截面,需计算各个节点截面特性,然后逐个输入;采用通用截面拟合工具输入函数,可一次完成。Using bridge doctor to compute variable cross - section continuous box girder, this paper states the modeling process of variable cross - section continuous box girder with single box and double room and inclined web. The box girder section is complex for its tope plate, bottom plate, web width and beam height are all variable and the beam bottom is twice parabolic curve. Using common method needs to compute the section characteristics of all nodes and input them one by one. Using general section fitting tool to input function can complete them at the same time.
