PURPOSE: A girder anchorage method by arranging a cable through a concrete curved box section is provided to control a sectional force concentrated in a cable insertion part by adjusting the insertion angle of a cable from the cable insertion part of a direction shifting block. CONSTITUTION: A girder anchorage method comprises the following steps: curvedly producing the web and lower flange of a cable support concrete box girder bridge; installing the web and the inside of the lower flange or the duct of an external block by curving in a lateral cross-sectional direction and sloping in the bridge axis direction; and inserting a cable into the duct and arranging the cable to traverse the lateral cross-section of a concrete box girder. |
