STRUCTURE AND CONSTRUCTION METHOD FOR BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a structure and construction method for a bridge that can construct a bridge of satisfactory quality in a period shorter than the conventional one. SOLUTION: The bridge comprises abutment units 1, pier units 2 and ribbed deck slab units 3 as members of precast concrete. The pier units 2 along a river are stressed with horizontal PC steel to constitute a multi-span rigid frame. The ribbed deck slab units 3 across the river are tensioned with PC steel to constitute a continuous beam. Both ends of the ribbed deck slab units 3 as the continuous beam and the abutment units 1 are tensioned with vertical PC steel to constitute a rigid frame structure. COPYRIGHT: (C)2004,JPO
