RESEARCH INTO THE CURVED BRIDGE WITH LARGE CURVATURE AND SMALL-SIGED GIRDERS

In this paper a series of problems concerning the design, theoretical analysis, model test and real structure test of small sized simply supported curved box-girder bridge are studied. The bending and torsion in the bridge are both fitted according to the theoretical calculation of cuved girders, thus providing a practical design method with enough precision for engineering practice. A set of construction technology for the erection of prefabricated box girders which suits our national condition are developed during construction of real bridges. The research would put a basis for the analysis of the curved structure converted from simply-supported condition.
