RZB型钻孔应变仪在青藏高原东缘地应力监测中的应用
Application of the RZB Borehole Strainmeter in Crustal Stress Observation at the Eastern Margin of the Tibet Plateau
摘要
Abstract
The authors introduce a new generation RZB borehole strainmeter and its application in crustal stress observation. The preliminary analysis of the monitoring data from the RZB-3A borehole strainmeter installed in crustal stress station of Jiangyou in Sichuan show that the resolution of the observing system is better than 10-9 strain megnitude. The borehole strainmeter not only recorded strain tide, also recorded broadband strain seismic wave. Especially, because of the superiority of the 4-component borehole strain observation, the obtained data show that RZB-3A borehole strainmeter has high measurement accuracy of plane strain in crustal horizontal strain field of the area around the observation station. Therefore, it is significant to reveal the relationship between the activity of stress field and earthquake to use the new multi-component borehole strainmeter to develop crustal stress continuous observation in the eastern margin of the Tibet Plateau.关键词
