A INTEGRAL ABUTMENT CONTINUOUS COMPOSITE BRIDGE USING PRECAST GIRDER AND THE CONSTRUCTION METHOD THEREOF

摘要

PURPOSE: A continuous composite bridge integrated with an abutment using a precast girder and a construction method thereof are provided to improve structural safety by applying compressive force for reducing negative moment to slab concrete. CONSTITUTION: A continuous composite bridge integrated with an abutment using a precast girder comprises abutments(13), a pier(14), outer and inner temporary construction materials, precast girders(33), slab concrete(36), abutment connecting concrete(39), and a bridge bearing(22). The outer temporary construction materials are formed on the top ends of the abutments. The inner temporary construction material is formed on the top end of the pier. The precast girders are installed on the outer and inner temporary construction materials, and compressive force is applied thereto. The slab concrete is placed on the tops of the precast girders. The abutment connecting concrete integrates the abutments and the precast girders with the slab concrete. The bridge bearing is installed between the pier and the precast girders.
