摘　　要：以不同斜交角度下整体式连续斜板桥为研究对象,提出了合理的钢筋配置方式.基于三弯矩方法,通过理论计算及有限元分析,总结了整体式连续斜板桥的实用计算方法,给出了实用计算图表.通过平面杆系的计算结果,查找相关系数即可以得到相应的配筋弯矩,简化了计算工作.Reasonable reinforcement method was proposed for integral continuous skew girder bridges with different skew angles.Based on the three-moment method,practical calculation method was summarized and solution charts were presented through the method of theoretical calculation and finite element analysis.The result indicated that based on the calculation results of plane rod system,the reinforcement moment of bridge structure could be gotten by looking up correlation coefficients and the calculation work was greatly simplified.
