高速铁路地震预警防护策略研究

Research of Protection Policy of Earthquake Monitoring and Early Warning System for High-Speed Railway

通过分析我国地震带分布、高速铁路规划,结合高速铁路地震预警的原理,提出了从点到线再到面的高速铁路地震预警防护策略,有效地应对地震灾害;基于上述防护策略,高速铁路地震预警试验在成灌高铁线和大西客运专线顺利实施,并成功监测到多次天然地震事件,发出预警信息;验证了高速铁路地震预警策略的可行性。

This paper analyzes the distribution of earthquake zone in China and the plan of high- speed railway. Combined with the principle of earthquake early warning of high-speed railway, the protection strategies of high-speed railway earthquake early warning is put forward to cope with earthquake disasters effectively. Based on those strategies, high-speed railway earthquake early warning test has been conducted smoothly in Datong-- xi＇an railway line and Chengdu-- Guanxian railway line and several natural seismic events were successfully monitored and early warnings were sent out, which validated the feasibility of the earthquake early warning strategy of high-speed railway.
