小浪底水利枢纽地震台网的数字化改造和应用

Xiaolangdi Hydro-junction Seismic Network Digital Improvement and Its Application

论述了小浪底大坝及其周边地震带分布情况,通过构建小浪底数字化地震台网,实现了全天候监控周边地震,并采用光纤传输数据实现了数据的实时监控、自动触发报警、全部地震事件采用人机交互分析处理。结果表明,地震台网能及时获得大坝及其周边的地震活动情况,为大坝安全提供了保障,可供借鉴。

This paper discusses the seismic zone distribution of Xiaolangdi dam and its surrounding. All-weather peripheral earthquake is monitored through construction of digital seismic network of Xiaolangdi dam. The optical fiber transmission data is applied to realize the real-time data monitoring, automatic alarm and human-computer interaction analysis for earthquake events. The results show that seismic network can timely acquire the seismic activity of the dam and its surrounding, which guarantees the dam safety. Thus, it can be used for reference.
