摘要
仙桃汉江公路大桥主桥是一座独塔不对称双索面预应力混凝土斜拉桥.为了保证其施工安全和成桥后主梁具有良好的线形,对该桥实施了施工监控.施工监控过程中采用了自适应卡尔曼滤波法对施工控制参数进行识别和预测.同时还介绍了该桥施工仿真计算、索塔和主梁的施工监控、阶段验收以及施工监控的工作程序等内容,为该桥的施工质量和安全提供了科学保证.
Xiantao Hanjiang Highway Bridge is an asymmetry prestressed concrete cable - stayed bridge with single tower and double cable planes. Construction monitoring was implemented in the bridge to ensure the construction safety and bridge girder with a good linear. In this paper, the construction control parameters were identified and predicted using the adaptive Kalman filter. At the same time, construction control simulation analysis, towers and beam construction monitoring, stage acceptance and the construction monitoring procedures were introduced. These provided scientific assurance for bridge construction quality and safety.
