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.
