施工工艺变化对斜拉桥施工监控的影响分析

Analysis of changing the construction process of the cable-stayed bridge during construction monitoring

结合斜拉桥施工监控实例,就斜拉桥施工方案变更的影响进行分析研究。阐述主梁根部块段由挂篮悬臂浇筑施工变为支架现浇对桥梁施工中的位移、截面应力及索力变化的影响。为设计变更及施工控制提供理论指导。

Combined with a cable-stayed bridge＇s construction monitoring, a analysis of changing its construction program is give＆ The influences of deflection and cross-section stress and cable force which are formed from the hanging basket to cast-in-place are discussed. Theoretical guidance for the design changes and construction control can be provided.
