摘要： 通过对新干线地震监测和紧急处置系统在日本地震中所起重要作用的分析，提出我国建设铁路地震监测和紧急处置系统的必要性.通过对国家强震动观测台网的真实地震数据分析，设置滤波器截止频率，提出基于低通滤波器、STA/LTA算法和V/H算法的P波识别技术，并对算法进行仿真.在此基础上，提出适合于我国铁路的基于P波预警加S波报警的地震报警方式，并分析不同情况下的报警条件.最后设计我国铁路地震监测及紧急处置系统方案，提出系统建设的三层架构，为保证系统报警的时效性，将紧急处置动作设置在沿线监控单元，所提出的系统方案对工程建设具有指导意义.

Abstract: It is necessary to establish the earthquake monitoring and emergency system by analyzing the important function of Shinkansens seismic emergency system on the Earthquake in Japan.The paper sets the cutoff frequency of the filter after analyzing the true earthquake data from China strong motion networks center.The method of Pwave recognition technology is proposed based on the low pass filter, STA/LTA algorithm, V/H algorithm and simulate the algorithm.Based on this, it suggests the earthquake alarm way based on the Pwave early warning and Swave alarm which fits for the railways in China.It also analyzes the alarm conditions in different circumstances.In the last part, the paper shows the earthquake monitoring and emergency system, which is constructed by three layers architecture.For maintaining the timeliness of systems alarm, it sets emergency disposal actions on the monitoring units along the line.The instructive significance of proposed system scheme is applicable for engineering construction.

Key words: railway transportation, Pwave recognition, filter, earthquake monitoring and emergency disposal, alarm conditions
