摘要
地震是人类不得不面对的一种自然灾害,研究地震的破坏规律、及时对地震可能产生的破坏进行警示、快速对震后烈度分布进行描述具有十分重要的社会意义。随着我国国际地位的提高及经济高速发展,越来越多的国内外基础设施由我国承建,因此,建立有效地震预警系统是十分必要的。地震烈度的快速描述及地震预警结果的计算离不开地震动参数的选取,依据国内外发生的多次地震,统计相关数据资料,分析包括加速度峰值PGA、累计绝对速度CAV等12种地震动参数与实际调查烈度的相关性,提出较为合适的地震烈度速报及预警计算参数。
Earthquake is one kind of natural disaster that human beings have to face.It has great social significance to study the damage rule of earthquake and warn the possible damage of earthquake in time.With the improvement of China's international status and rapid economic development,more and more domestic and foreign infrastructure is contracted by China,so it is very necessary to establish an effective earthquake warning system.Reasonably selecting ground motion parameters closely related to the actual investigation intensity has very important earthquake warning value.Based on the data of several earthquakes in China and abroad,this paper analyzes the correlation between various ground motion parameters and the actual investigation intensity,and puts forward more appropriate calculation parameters for earthquake early warning.
