摘要
笔者对简支曲线小箱梁桥型的设计、理论计算、模型与实桥试验作了系列研究 ,并以曲线梁理论计算为依据进行弯矩拟合和扭矩拟合 ,为实际工程应用提供了一种具有足够精度的实用计算方法 .在实桥施工中摸索出一套适合我国国情的预制曲线小箱梁的施工工艺 .
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 curved 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.
