PGV:峰值地面速度
峰值地面速度(Peak Ground Velocity,常缩写为PGV)是地震工程与地质学领域中的一个重要专业术语,用于描述地震发生时地表振动的最大瞬时速度。这一指标对于评估地震对建筑物和基础设施的潜在破坏性具有关键作用。PGV的缩写形式在学术文献和技术报告中广泛使用,便于快速书写和交流。
Peak Ground Velocity具体释义
Peak Ground Velocity的英文发音
例句
- It is recommended that the peak ground velocity ( PGV ) and ground energy density ( E () are the parameters that can be used to estimate the damage degree of structures in the near-field environment.
- 在近场环境峰值地面速度(PGV)(PGV)和地震动能量密度(Eρ)可用来较好地估计结构的破坏程度。
- Under the premise of fitting the target acceleration response spectrum, the peak ground velocity is obtained by a separate adjustment of long period component of the ground motion Fourier Spectrum.
- 在拟合目标加速度反应谱的前提下,通过单独调整傅立叶谱中较长周期成分来控制合成地震动峰值速度和位移。
- The E_H / E_I ratio for the mass-proportional damping model is the biggest one, with the increase of peak ground velocity to acceleration ratio ( V / A ), the E_H / E_I ratio for the Rayleigh and stiffness-proportional damping model will be close to mass-proportional damping model.
- 采用质量比例阻尼模型计算获得的结构滞回耗能比最大,随着地震波峰值速度与峰值加速度比值(V/A)的增大,刚度比例和瑞雷阻尼模型的计算结果会与质量比例阻尼模型趋于一致。
- The outcomes indicate that under the effect of velocity pulse the increment of PGD ( peak ground displacement ) is greater than that of PGV ( peak ground velocity ), which has less influence on PGA ( peak ground acceleration ).
- 结果表明:在速度脉冲效应下,地震动峰值位移增大值大于峰值速度增大值,而峰值加速度所受影响最小。
