Abstract  In this paper the vibrat ional characterist ics of the earth surface collided by a free-falling hammer are first analysed. The dynamic model is established and the displacement , velocity and acceleration of the vibrat ion system are obtained. The self-pow er spectrum of the vibration system are disccused by
using FFT.

Key words： vibration      surface wave method      spectrum analysis

落锤撞击地面振动的初步研究

首先分析了落锤撞击地面的振动特性，并进一步建立了落锤及土体振动模型，利用这一模型得到了振动体系的位移、速度及加速度，进一步通过傅立叶变换（ＦＦＴ）研究了振动体系的自功率谱。
