Ballastless track structure state monitoring method
The invention relates to a ballastless track structure state monitoring method, the method comprises the following steps: in the ballastless track construction process, configuring a fiber bragg grating array temperature measuring optical cable and a fiber bragg grating array stress optical cable in a base plate and/or a track plate, and monitoring a temperature state in a base plate/track plate forming process through the fiber bragg grating array temperature measuring optical cable, and monitoring the stress state in the forming process of the base plate/track plate through a fiber grating array stress optical cable, judging whether the quality of the base plate/track plate meets the requirement or not according to the obtained temperature state and stress state, and performing corresponding maintenance operation on base plate concrete/track plate concrete. The construction quality of the ballastless track can be effectively improved, corresponding monitoring work is conducted through the fiber bragg grating array optical cable, on-site installation is convenient, data channels are few, the influence on the concrete structure of the base plate/track plate is low, and data collection reliability and accuracy are high.
本发明涉及一种无砟轨道结构状态监测方法，在无砟轨道施工过程中，在底座板内和/或轨道板内配置光纤光栅阵列测温光缆和光纤光栅阵列应力光缆，通过光纤光栅阵列测温光缆监测底座板/轨道板成型过程中的温度状态，以及通过光纤光栅阵列应力光缆监测底座板/轨道板成型过程中的应力状态，根据所获得的温度状态和应力状态判断底座板/轨道板的质量是否符合要求以及对底座板混凝土//轨道板混凝土进行相应的养护操作。本发明能有效地提高无砟轨道的施工质量，采用光纤光栅阵列光缆进行相应的监测工作，不仅现场安装方便，数据通道少，对底座板/轨道板的混凝土结构影响较小，而且数据采集可靠性和准确度高。
