| Abstract: | The bridge axial alignment is a key point to bridge bearing capacity evaluation,disease analysis,health analysis and taking-over inspection.However,the routine technique is costly both in time and in finance,and what's more,the preciseness of the inspection can't be guaranteed.Taking the main arch axial alignment of an existing arch bridge as an example,the dihedral method in measuring bridge axial alignment is introduced.The experiment proves that the discussed technique is reliable,precise,simple and practical. |
