Consequently, it is necessary to describe earthquake ground motion with local spectral density, which is time-dependent and can reflect the non-stationary characteristics.
因此采用能反映时频非平稳特性的时变谱密度(即局部谱密度)来描述地震地面运动是非常必要的。
But in this paper, we lay emphasis only upon analyzing the influence of soil layer characteristics on ground motion.
本文着重考虑了土层的特性对地面运动的影响。
The design ground motion time histories was synthesized for the Shahuan Nuclear Power Plant Site according to the characteristics of the site and the specifications of input motion in the paper.
本文根据广东沙环核电厂厂址地震地质环境特点和有关核法规的技术要求完成了设计地面运动时程的人工合成。
