摘要
为了研究开发更经济、更简便的场地动力特性探测方法，本文简要地回顾了工程场地条件评定中地脉动研究的演进，概述了地脉动观测技术的发展，循着地脉动分析方法的演进历程，叙述了谱和谱比分析方法、利用地脉动频散曲线反演场地速度构造的研究，讨论了各种分析方法的依据和适用条件，指出了目前存在的问题，并探讨了可能的改进途径。
In order to develop a more economical, simple and convenient approach for exploring the dynamic characteristics of engineering site, the authors briefly overview the evolution of microtremor study in site rating in this paper. The development of microtremor observation technique was sum marized. Spectra and spectra ratio analysis method and the study on inversion of site shear wave velocity structure by means of dispersion curve are introduced. The basis and the applicability of of methods, the shortcomings at the present stage, and the possible improving paths are discussed.
