GEOPHYSICAL EXPERIMENTS OF KM SIZE AND CHARACT-ERISTICS RECORDED IN THE SOURCE REGION

Institute of Geophysics, State Seismological Bureau, Beijing, China

摘要

摘要: 文中首先简述了岩石力学实验、震源物理研究、地震预报中的一些结果,这些研究提出的共同问题是需要进行中等尺度(公里量级)的地球物理实验.其次介绍了北京门头沟的公里尺度地球物理实验场的概况.最后给出了目前已取得的一些进展,如地表记录与地下记录的差异、微破裂的应力降与介质应力状态的关系、介质背景噪声的主频率与介质应力状态关系、震源体上记录的特征等.

Abstract: This paper first shows some results obtained by rock mechanics experiments,source physics research,and earthquake prediction. The common problems involved in those researches need to be solved by geohysical experiments of medium size (of km size). It also gives a summary about the geophysical experiment field of km size in Mentougou,Beijing. Finally,Some results obtained up to the present are given,such as the differences between records on the surface and underground; the relation between stress drop of microfractures and stress state; the relation between the predominant frequence of background noise and stress state of the media; as well as characteristics of records recorded in the source region.
