地震运动 meaning in Chinese
earthquake ground motion
seismic motion
Examples
- The world is girded by chains of active volcanoes and rent apart by frequent earthquakes
事实上，那克土恩就是这样一个由接连不断的火山和地震运动构成的星球。 - Based on the basic principles of dynamical analysis by using finite element method , formulas for back - evaluating the stochastic seismic characteristics of the bedrock from the stochastic seismic characteristics of the ground surface were derived by using the impulse - response function and the principles of fourier transform . a method of back analysis for this purpose is put forward . the example shows that the ground has an obviously amplifying effect for seismic motion
6从有限元动力分析的基本原理出发，利用脉冲响应函数和傅立时变换对原理，推导了由地面地震运动特性反算基岩地震运动特性的反分析计算公式，提出了一种用于由地面地震动特性计算基岩地震动特性的二维有限元反分析方法。
