摘要
通过地震危险性分析计算,认为场地地震动持时主要决定于近场地震影响;潜在震源区震级上限越大,场地地震动持时越大;潜在震源区其它地震活动性参数(年发生率、起算震级、b值)减小或设防水准降低,场地地震动持时增加,且地震动持时增加幅度较小。
Based on the seismic risk analysis, some results are obtained as follows: the seis- mic duration in site is mainly dependent on near field earthquake effects, the larger the magni- tude in latent source zone, the bigger the site ground motion is; Other seismicity parameters (such as V, Mob) have few influences on the seismic duration.
