摘　　要：钢结构箱形梁具有刚度大、自重轻和便于现场安装等优点,已成为城市大跨度、小半径曲线桥梁常用的结构形式。曲线钢箱连续梁对日照温度效应非常敏感。主要归纳了国内外关于钢结构箱梁桥日照温度的相关研究和规定,并对曲线钢箱梁的日照温度效应进行探讨。Steel bridges with box girder have become a common structural style in the large span and little radius curved bridge, owing to its advantages such as good rigidity, light weight and easy constructing, etc. Curved steel bridge with box girder is sensitive to the sunlight temperature effect. In the paper, the related study and bridge criterion at home and abroad about sunlight temperature effect of bridge are summarized, and the sunlight tempe-rature effect of the steel curved bridge is also dis-cussed.

关 键 词：曲线桥梁 钢箱梁 日照温度效应 变形
