曲线梁桥设计理论述评

曲线梁桥是交通工程中的一种重要桥型。本文综合论述了现有曲线梁桥的计算理论和计算方法,将曲线梁桥的现有设计理论归纳为:纯扭转理论、约束扭转理论、梁格理论、横向分布理论等。并在此基础上,提供了典型设计实例。本文为曲线梁桥设计理论的进一步研究及工程设计均提供了有意义的参考。

Discussing On The Design Theory Of Curved Girder Bridge

The curved girder bridge is an important bridge type in traffic engineering. The theory and the methods of calculation for curved girder bridge are reviewed in this paper. The existing design theory of curved girder bridge can be reduced to some kinds as below: pure torsion theory, restricted torsion theory, bridge pattern theory, landscape orientation distributing theory, etc. Base this, some important ideas about designing of curved girder bridge are put forward through designed example. It provides some reference for more study and engineering design.
