高速铁路行车组织地震预警处置策略研究

Research on the Disposal Strategy of Earthquake Early Warning for High Speed Railway

为优化地震影响范围外列车的运行,便于地震后乘客疏散和行车组织的恢复,提出一种基于运行图数据的高速铁路地震预警处置策略。根据铁路运输性质和地震对铁路危害的特点提出高速铁路震后列车运行规则,并以此为约束条件构建高速铁路地震预警处置策略,通过编程建立地震预警处置策略模型。以京沪高速铁路为实例进行仿真验证,结果表明,高速铁路地震预警处置策略可以根据车站容纳能力准确地对地震影响范围外的列车进行震后处置,在保证行车安全的基础上减少了地震对路网运行的影响,提高运行效率。

To optimize train operation outside the scope of earthquake impact and facilitate the passenger evacuation and the reorganization of operation plans after earthquakes, this paper proposed a disposal strategy of earthquake early warning for high speed railways based on the data of train diagrams. According to the nature of railway transportation and the characteristics of earthquake damage to railways, this paper established the rules of train operation after the earthquakes and the disposal strategy based on the constraints. The strategy model was built by programming and the simulation was verified with the data of the Beijing-Shanghai high speed railway. The results show that this strategy can accurately dispose the trains outside the earthquake influence area according to the station capacity, reducing the impact of earthquakes on railway operation on the premise of safe railway operation and improving the operation efficiency.
