| 摘 要： | 针对城际铁路观测资料中,对断高数据处理不能准确反映线下工程沉降量的问题,结合卡尔曼滤波模型的优点,提出一种基于高差观测值的卡尔曼滤波模型断高数据处理新方法,并详细阐述了新方法实现的思路和具体步骤。通过武咸城际铁路工程实例验证,比较和分析了新方法与传统方法的结果,得出新方法能够使得观测资料更加真实地反映线下工程实际沉降量的结论,说明了该方法的可行性和有效性。

| Abstract: | In inter-city railway settlement observations,the traditional method for fault data processing can not accurately and truly reflect the settlement of the project under line.This article proposes a new Kalman filtering model based on height difference for fault data processing and introduces concepts and and the steps of the new method in detail.Verified with the Wu-Xian inter-city railway project,the results of the new method are compared with the traditional method.The new method for inter-city railway can more accurately and truly reflect the settlement of the project under line and it is feasible and effective. |
