BRIDGE HAVING CONTINUOUS ARCH HYBRID GIRDERS AND THE BRIDGE CONSTRUCTION METHOD USING THE SAME

摘要

PURPOSE: A construction method of an arch-shaped composite girder bridge of a continuous span is provided to reduce required materials by remarkably reducing the cross section of a composite girder. CONSTITUTION: A construction method of an arch-shaped composite girder bridge of a continuous span is as follows. Girder steel members(112) are manufactured in a construction field. Sheath pipes(122) are installed inside the girder steel members. The girder steel members are partially filled with concrete. The concrete is cured. Arch-shaped composite girders(110) are manufactured by installing tendons(160) in the cured concrete of the girder steel members. The composite girders are transferred from the construction field to a bridge construction position and is installed to be contiguous to an abutment(170) or a pier(172).
