According to the characteristics of the arch bridge′s structure, a blasting program of charging more explosives in the borehole of mounds and arch feet than normal blasting and released blasting for the arch top and belly arch mound is used.

And through the forced comparison between plumb pile and battered pile it thinks that the battered pile is favorable more than plumb pile in forced aspect in arch type bridge project.

Rational internal force of hangers under different construction stage can be obtained through optimization analysis of the object under the finished bridge condition of the camber composite bridge.
