The invention relates to the technical field of railway monitoring, and discloses a high-speed railway ballastless track roadbed service performance evaluation method and system, and the method comprises the steps: determining a patient interval through an air monitoring system, determining a poor track interval through a vehicle monitoring system, dividing a risk road section and a patient road section according to the patient interval and the poor track interval, and carrying out the evaluation of the service performance of a ballastless track roadbed. Then track dynamic response data of the risk road section and the patient road section are obtained through a track monitoring system, and roadbed static and dynamic response and physical state data of the risk road section and the patient road section are obtained through a ground monitoring system; and calculating an evaluation index coefficient of the service performance of the ballastless track roadbed based on the track dynamic response data and the roadbed static and dynamic response and physical state data, thereby obtaining a service performance evaluation result corresponding to the ballastless track roadbed according to the evaluation index coefficient. The ballastless track roadbed service performance evaluation method solves the problems that an existing ballastless track roadbed service performance evaluation method is low in efficiency and accuracy.

    本发明涉及铁路监测技术领域,公开了一种高速铁路无砟轨道路基服役性能评价方法及系统,包括:通过对空监测系统确定病患区间,通过对车监测系统确定轨道不良区间,根据病患区间和轨道不良区间划分风险路段和病患路段,再通过对轨监测系统获取风险路段和病患路段的轨道动态响应数据,通过对地监测系统获取风险路段和病患路段的路基静动态响应及物态数据,便可基于轨道动态响应数据和路基静动态响应及物态数据计算无砟轨道路基服役性能的评价指标系数,从而根据评价指标系数得到无砟轨道路基对应的服役性能评价结果;本发明解决了现有的无砟轨道路基服役性能评价方法存在效率低下、准确性较低的问题。
