摘　　要：以无锡市凤翔快速路堰裕路跨线桥为工程背景,对曲线梁桥的整体调坡顶升方案进行系统研究,并就曲线梁桥调坡顶升过程中,对顶升施工中顶升反力、钢支撑稳定、钢分配梁进行计算,验证施工方案的安全性和合理性;通过整体交替顶升分步到位,保证曲线梁桥达到设计标高;并就曲线梁桥调坡顶升后横坡变化采取顶升调平措施防止顶升过程中盖梁的横坡变化对箱梁的影响,相关技术方案及施工方法可为类似桥梁工程提供参考。With the crossing bridge as the engineering background,the whole curve beam jacking scheme is systematically studied,the jacking reaction force,steel support stability and steel distribution beam and ensure that the curve beam bridge reaches the design elevation.The relevant technical schemes and construction methods can provide a reference for similar bridge engineering.
