After describing the diseases on hinge joints of the hollow plate and analyzing causes, eight reinforcement measures are put forward and introduced herein accordingly. By means of solid finite element analyzing method, the article conducts a contrastive analysis on a variety of working conditions of those eight reinforcement measures, including the hinge joint stress and transverse distribution parameter. Three ideal methods are selected to conduct further analysis on the reinforcement effect of the hinge joint stress and it is concluded that there is risk in one way steel beam hinge joint reinforcement and two ideal methods are two-way steel beam reinforcement and adding transverse diaphragm in precast phase. From the perspective of fundamental solution to hinge joints, two-way reinforcement exerts more obvious effect on the bridges in service while adding transverse diaphragm is better for newly built bridges. Making it easy for design and construction, this paper offers constructive reference for engineering practice by deducting the vertical arrangement distance of the steel beam, presenting needs to be met by the shear resistance and flexural bearing capacity after verifying reasonable distance, discussing numbers and distance of transverse diaphragm and summarizing the strain of the external prestressed steel beam.
