摘要:

结合PC曲线梁桥的力学特征，梳理国内规范曲线梁桥的相关条文，从分析方法、支承体系影响、桥墩高度和支座刚度、恒载扭矩、预应力效应、支座横向偏心等方面总结小半径PC曲线梁桥的分析要点，从构造设计、钢束设计、钢筋设计、附属设计等方面总结小半径PC曲线梁桥的设计要点，相关结论可为设计人员提供参考。

Abstract:

Combined with the mechanical characteristics of PC curved beam bridge, the relevant provisions of the domestic standard curved beam bridge are sorted out. The analysis essentials of small-radius PC curved beam bridge are summarized from the analysis method, supporting system, pier height, support stiffness, constant load torque, prestressing effect, support lateral eccentric and the other aspects. The design essentials of small-radius PC curved beam bridge are summarized from the structural design, steel tendon design, rebar design, auxiliary facility design and the others. The related conclusions can provide reference for the designers.
