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 .对这种桥型的研究将为先曲线简支再变成连续结构的分析奠定了基础 The author made a series of researches on the design, theoretical calculation, model and experiment of simple box girder bridge with simple support curve, and carried out the bending moment fitting and torque fitting based on the calculation of curve beam theory, which provided the practical engineering application A kind of practical calculation method with enough accuracy.From the real bridge construction, we found out a set of prefabricated curved box girder construction technology that suits the national conditions of our country.Study on the bridge type will be the first of which will be the simple structure of the curve first, then the continuous structure The analysis laid the foundation
