摘　　要：针对工程中常用的曲线桥梁设计与计算方法进行了分析,指出目前常用的曲线桥梁计算有两种方法,一种是空间单梁模型,另一种是空间梁格模型,着重介绍了箱形梁的梁格法理论,从梁格理论单元的划分、各单元截面特性以及梁格划分考虑的因素等方面进行了论述。The curved beam bridge design and calculation method against to engineering common use were analyzed. It pointed that there were two methods of curved beam bridge calculation, one was spatial single beam model, and the other was spatial gridiron model. The gridiron theory of box beam was emphasis introduced, which was illustrated from gridiron theory unit division, every unit cross section characteristic and gridiron division considered factors.
