strong ground motion的意思|示意

This modification incorporates explicitly the duration of strong earthquake ground motion into the time dependent variation of the root-mean-square peak amplitude.

这个修正明显地将强震运动的持续时间包含在均方根振幅依赖于时间的变异中。

A new method and steps of setting up a finite fault source model of a scenario earthquake on an active fault for predicting near-fault strong ground motion are proposed here.

提出了近断层强地震动预测中建立活断层上设定地震有限断层震源模型的方法和步骤。

The ground acceleration here must have been very high and the duration of the strong motion long to cause such incredible destruction.

当时地表加速度一定很高，而且强烈震动的时间很长，造成了如此严重的破坏。

Based on the Hanyuan seismic investigation, the damage situation was introduced, and the data on strong ground motion and soil mechanic parameters in and near Hanyuan county were collected.

在汉源科学考察基础上，介绍了汉源震害情况，收集和整理了汉源县城及附近有关工程场地的强震和土体力学参数资料。

A method for predicting the phase spectra of strong ground motion is presented based on the equivalent dispersion of wave motion and the approach for synthesizing ground motions is then studied.

本文在强震地震波频散研究的基础上，进行了强地震动场相位预测方法和多点地面运动时程合成方法的研究。

Then, a seismic design method considering the effect of strong ground motion duration is presented.

从以上结果出发，本文提出了一个考虑地震中不同持续时间影响的抗震设计方法。
