PURPOSE: A construction method of a PSC girder bridge using an anchorage capable of adjusting tension is provided to improve the prestressing effectiveness of a steel wire, to secure the stability by replacing a bottom plate in the state in which tension of a steel wire is removed, and to economically construct a bridge having the low height and long span. CONSTITUTION: A construction method of a PSC girder bridge using an anchorage capable of adjusting tension comprises the steps for installing a primary steel wire(1) in a PSC girder(10), inducing the primary tensile force by tensioning as much as the weight the PSC girder and the weight of a half-section precast deck, temporarily installing the PSC girder onto a pier or an abutment, installing the half-section precast deck on the PSC girder, inducing the secondary tensile force by tensioning the secondary steel wire arranged in the PSC girder longitudinally arranged in a row, and constructing a concrete deck slab over the whole span by spreading concrete on the half-section precast deck. |
