Taking a prestressed concrete continuous box girder bridge as an example,according to the standard of bridge design,this paper analyzes and studies the crack resistance of the normal and oblique section of the box girder.The results show that the design of the main girder can meet the specification requirements,and the research provides a theoretical reference for the design of the bridge engineering.%以某高速公路段上预应力混凝土现浇连续箱梁桥为例,根据桥梁设计的标准,对正常使用阶段箱形梁主梁的正、斜截面的抗裂进行分析研究.计算结果表明:主梁设计满足规范要求.研究为桥梁工程设计提供了理论参考.
