仪器烈度计算离不开各种地震动参数,然而众多研究结果表明,仪器烈度与实际调查烈度相吻合的程度较低,这给我们进一步开展相关研究工作带来了不少困难。在广泛收集强震观测记录和实际调查烈度这两种资料的基础上,通过数学方法引入了等效地震动参数这一概念,很大程度上提高了仪器烈度与实际烈度相一致的比例。研究结果表明,等效地震动参数在烈度速报中有着广阔的应用前景。 However, numerous research results show that the degree of coincidence of the instrument intensity with the actual survey intensity is relatively low, which brings a lot of difficulties for us to further carry out related research work. On the basis of extensively collecting the data of strong earthquakes and actual survey intensity, the concept of equivalent seismic parameters is introduced through mathematical methods, which greatly improves the proportion of instrument intensity to actual intensity. The results show that the equivalent seismic parameters have a broad application prospect in the speed report.
