摘要
随着大众审美水平的不断提高,越来越多的异形复杂景观桥梁被提出,为确保该类桥梁在施工过程中结构安全稳定,对桥梁进行必要施工过程监控。以安吉云上草原景区景观斜拉平台为背景,基于系统化监测技术,对该桥施工过程中索塔、平台梁、拉索等关键构件的应力与变形进行监测,并与有限元理论计算结果进行比较,分析总结了实测值与理论值之间出现误差的原因,为类似异形单悬臂斜拉桥施工监控提供参考。
With improvement of public aesthetic level, special-shaped and complex landscape bridges are proposed. The bridges in the construction process should be monitored to ensure the structural safety and stability. Taking a landscape cable-stayed platform of Anji Sky Land as the case, the stress and deformation of key components such as cable tower, platform beam, and cable during the construction of the bridge are monitored with the systematic monitoring technology. The reasons for the error between the measured value and the theoretical value are analyzed and summarized.
