地震动峰值加速度 ground motion peak acceleration
- 研究结果表明利用地震动峰值加速度对地震诱发崩滑进行研究具有一定理论和实际意义。
The results demonstrate that it is useful in both theory and practice to study earthquake-induced landslides with PGA. - 文章最后给出了美国西部考虑震源破裂方向的地震动峰值加速度和均方根加速度的衰减关系。
Finally, the formulas of PGA and RMS accelerations attenuation dependent on the rupture direction of the seismic source are presented for the Western United States. - 作为地震动强度指标,峰值加速度一直是研究最多的物理量。
As the intensity index of ground motion, PGA (peak ground acceleration) is often employed and analyzed.
