CONSTRUCTION METHOD FOR CONTINUOUS BRIDGE USING CONFINED CONCRETE

摘要

PURPOSE: A construction method of a continuous bridge using a constraint concrete is provided not to generate a harmfulness deformation in a steel girder even though applying a pre-stress force. CONSTITUTION: A construction method of a continuous bridge using a constraint concrete comprises the following steps: a pre-stress force is applied by settling a lower part tendon material on a lower part anchorage of a steel girder (11) of multiple positive moment sections; the steel girder of the multiple positive moment sections and a steel girder (12) of multiple negative moment sections unite alternately by mounting; an upper constraint concrete (21) is placed in an upper part of the steel girder of the multiple positive moment sections; and the pre-stress force is removed, and a slab concrete (30) is placed in an upper part of multiple steel girders (10).
