一种适用于高铁沿线的多台站快速地震预警方法

对于地震预警技术来说,根据参与监测预警的台站数量不同,可以将高速铁路地震监测预警系统分为单台站地震P波预警技术和多台站地震P波预警技术。单台站P波预警由于信息量较少以及噪声影响,在定位方面存在较大误差。多台站P波预警技术是在单台站P波预警的基础之上,综合多个单台站信息进行综合震源参数估算并发出地震预警信息的预警方式。通过应用多台站P波预警定位技术,能够在震源估算方面得到更准确的结果。

A Fast Earthquake Early Warning Method for Multi-Stations Along the High Speed Railway

For earthquake early warning technology,according to different numbers of stations participating in monitoring and early warning,the high speed railway earthquake monitoring and early warning system can be divided into single-station earthquake P-wave early warning technology and multi-stations earthquake P-wave early warning technology.Due to the small amount of information and the influence of noise,single-station P-wave early warning has large errors in location.The multi-stations P-wave early warning technology is an early warning method based on single-station P-wave early warning that integrates information from multiple single stations to estimate integrated earthquake source parameters and issue earthquake early warning information.By applying multi-stations P-wave early warning location technology,more accurate results can be obtained in terms of source estimation.
