Reinforcing method for assembly type web arch ring of two-way curved arch bridge

The invention discloses a reinforcement method for an assembly type web arch ring of a two-way curved arch bridge. The reinforcement method comprises the following steps that the damage of the assembly type web arch ring is repaired; a reinforced concrete lattice is arranged on the bottom face of the assembly type web arch ring and comprises longitudinal ribs and transverse ribs which are distributed in a criss-cross mode. And after the construction of the reinforced concrete lattice on the bottom surface of the web arch ring is completed, carrying out surface sealing treatment on the exposed crack. The longitudinal ribs and the transverse ribs are combined in a staggered mode to form reinforced concrete lattices, the web arch ring stress shed frame is jointly formed, the bearing capacity of the web arch ring is effectively improved to meet the road network traffic requirement, meanwhile, the sparse transverse ribs do not completely limit the displacement coordination function of the web arch ring, and the fu
