摘要
在新版《公路钢筋混凝土及预应力混凝土桥涵设计规范》(JTG 3362-2018)颁布之际,结合实际工程实例,分析曲线上的现浇箱梁在设置墩间单支座时支座脱空情况,并进一步探讨曲线现浇箱梁支座预偏心对桥梁支座脱空问题的影响,为曲线桥梁稳定性设计提供参考。
《Specifications for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts》(JTG 3362-2018) has been promulgated. Combined with practical engineering example,analysis the bearing empty of cast-in-situ box girder on the curve when a single bearing in the piers are installed,and further explore the influence of bearing eccentricity of cast-in-situ box girder on the curve. Provide reference for design of curve bridge stability.
