摘要

本研究采用在轨道更新时埋设在轨道床中的光纤，测量轨道的垂直支撑和压力分布。利用分布式声传感器(DAS)系统，通过测量传感光纤上压力引起的应变变化，获得了压力分布。DAS系统的实验结果与履带床的数值模型吻合较好。

Trackbed behavior analysis based on distributed acoustic sensor

In this study, an optical fiber, buried in the trackbed during track renewal, is used to measure the vertical support and pressure distribution of the track. The pressure distribution was obtained using a distributed acoustic sensor (DAS) system by measuring the pressure-induced strain changes on the sensing fiber. The experimental results obtained by the DAS system show a good agreement with the numerical model of the trackbed.
