| Abstract: | 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. |
