| Abstract: |
| This paper studies the Least Square Method to define high-speed railway (HSR) earthquake risk and solve the problem of its emergency response mechanism. Based on the construction of a monitoring system for HSR earthquake emergency response, the technical operational procedures for HSR seismic emergency response are proposed. The quantity, scale, and location of HSR earthquake emergency response mechanism are defined, and the corresponding emergency response system is built. In particular, the earthquake emergency response system can conduct real-time continuous dynamic monitoring of seismic activity along the railway. When earthquake occurs, the intensity of the ground motion is detected by the system. When the earthquake monitoring value reaches the earthquake alarm threshold, it will send an alarm signal to the dispatch center, and the emergency power supply will be forced to cut off. The earthquake emergency response system will continue to monitor the follow-up ground motion acceleration. The system provides the operation scheduling center with a basis for train operation control to resume operation after stopping. The monitoring result of the system reduces the disaster, and the secondary disaster is caused by the earthquake. This paper improves the HSR response mechanism in detecting earthquake disasters. The result improves the ability of HSR to deal with earthquake disasters, and reduces casualties and economic and property loss caused by earthquake disasters. |

| 最小二乘法的高速铁路地震应急处置系统 胡启洲，吴翊恺 （南京理工大学 自动化学院，南京210094） 摘要：针对高速铁路地震的风险界定及应急处置问题，利用不确定性数学方法进行研究。主要在构建高速铁路地震应急处置的监控体系基础上，提出高速铁路地震应急处置技术操作性程序，界定高速铁路地震应急处理应该具备的数量、规模和位置，并搭建相应应急处置系统。特别是地震应急处置系统对铁路沿线地震活动进行实时连续动态监测，当地震发生时，系统检测到的地震动强度达到地震报警阈值时向运营调度发出警报信号，并紧急断电强制停车；同时，继续监测后续的地震动加速度，以向运营调度提供停车后恢复运营的列车运行管制依据，从而减轻因地震引发的灾害损失并防止因地震引发的次生灾害损失，达到提高高速铁路对地震灾害的处置能力，减少地震灾害带来的人员伤亡和经济财产损失。 关键词：高速铁路，地震监控，应急处置模式 |
