摘要
为保证高速铁路运行安全,必须在运营阶段加强桥梁的监测,并对桥梁的变形作出预测。本文结合津秦客运专线桥梁区段地基沉降监测,采用双曲线法和卡尔曼滤波法对桥墩的沉降预测进行了理论研究,并与同一组桥墩沉降观测数据进行对比,说明采用卡尔曼滤波法进行预测的结果符合墩台沉降变形规律,能比较准确预测桥墩的最终变形。
In order to guarantee the operation safety of passenger-dedicated railway, the bridge monitoring must be reinforced in operation stage and bridge deformation should be predicted as well. Combining with ground settlement detecting of bridge segment on Jing-Qin passenger-dedicated railway, this paper introduced the pier settlement prediction theory according to Hyperbola method and Kalman filter method and analyzed the pier settlement observation data in the same group, which illustrate that the Kalman filter method for predicting is in accordance with the pier settlement deformation principle and can obtain the final deformation model.
