摘　　要：对箱涵工程计算及受力分析一般都采用斜交转正交的平面框架计算模型,但是对于斜偏角大于30°的箱涵,框架模型计算的结果误差会很大。基于工程实例,考虑施工简单等因素,对箱涵计算模型进行修正,利用斜长作为斜交转正交计算模型的结构尺寸进行验算,并在此基础上对箱涵配筋进行优化。The plane frame calculation model of oblique to normal intersection is generally adopted for box culvert engineering calculation and force analysis. However, for box culverts with slant angle greater than 30 degrees, the calculation error of frame model will be very large. Based on the engineering example, considering the simple construction and other factors, the calculation model of box culvert is revised, and the inclined length is used as the structure size of the calculation model of oblique to normal intersection, and the reinforcement of box culvert is optimized on this basis.
