| Abstract: | Based on engineering practice,it introduces structure composition,material request and setting up model of bottom pushing steel box arching method consolidating hyperbola arch bridge,research makes clear that adopting bottom pushing steel box arching method to consolidate hyperbola arch bridge can decrease deformation of original structure effectively,reduce stress lagging effect of add-on structure,it can display intensity capability add-on material and reach a good synthetic effect. |
| Keywords: | hyperbola arch bridge steel box arching consolidate design |
