| 摘 要： | 与远场地震动相比,近断层(也称为近场或近源)地震动呈现了更复杂的破坏特性,但迄今,对该区域却没有明确划分,只是依主观选择.为解决这一问题,本文详细比较了近断层与远场地震动特征参数的差别,结果表明,近断层地震动的峰值加速度、峰值速度、峰值位移、能量密度以及竖向与水平向峰值加速度的比值同远场差别较明显,而水平向峰值速度与峰值加速度比和竖向峰值速度与峰值加速度比的差别不大.依据近断层与远场存在差别的这些地震动特征参数,划分了近断层地震动区域. |

| Abstract: | Compared with far-field ground motion,more complicated characteristics appear in near-fault(near-field or near source)ground motion.In order to include these effects in seismic codes,it's necessary to determine the scope of near-fault ground motion.However,there is no clear definition to divide this scope and it is decided with subjective assessment until now.In this study,characteristic parameters that can describe near-fault and far-field ground motion are compared.It is showed that there is relatively si... |
| Keywords: | scope of near-fault near-field near source scope |
