【摘要】 中国数字强震动台网作为"十五"重大项目中国数字地震观测网络的重要组成部分之一,是迄今为止我国投资最多、规模最大的强震动观测台网。由于台网采用了多种数字强震动仪,不同型号数字强震动仪的一致性程度直接影响到台网的观测质量。通过对台网所用5种数字强震动仪的振动台试验和结果分析,表明这5种数字强震动仪的一致性良好,能够满足中国数字强震动台网建设要求。更多还原

【Abstract】 As an important part of China Digital Seismic Observation Network,China Digital Strong Motion Network(CDSMN) aims to be the prime national strong motion observation network,and it has got the bigger investment than ever.As several types of accelerograph are used in CDSMN,the consistency between different observation systems affects directly the accuracy or the data of CDSMN.Vibration table tests of the 5 types of accelerograph adopted in CDSMN are presented togather with the result analysis in this paper.Base on these tests,the consistency can be trusted for CDSMN.更多还原
