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。
According to the inter-city railway observation data, the problem that the data processing can not accurately reflect the subsidence of the line project is analyzed. Based on the advantages of the Kalman filter model, a new Kalman filter model is proposed based on the observed data of elevation difference. Method, and elaborated the idea and concrete step that the new method realizes. The results of the new method and the traditional method are compared and analyzed by the Wu-Xiang inter-city railway project. The conclusion that the new method can make the observed data more truly reflect the actual subsidence of the line project is obtained, and the feasibility and effectiveness of the method are demonstrated Sex.
