| 摘 要： | PBO(Plate Boundary Observatory)计划专门设计了一批钻孔应变仪台.网,在数百米距离内,安装2～3台仪器,以研究钻孔应变仪如何响应构造活动的信号,以及局部因素会造成何种干扰.本文收集了6个这样的台网的资料,给出了所有仪器数年的记录曲线,并对观测结果显示的地壳应变场做了简要的分析对比,发现6个试...

| Abstract: | Several clusters of borehole strainmeters were specially established in PBO,in which 2 or 3 instruments were installed within a few hundred meters to study how the borehole strainmeter responds to tectonic activities and what interference will be generated by local,non-tectonic factors.Data of 6 such clusters were collected and presented in the paper.The crustal strain field revealed at the data and a brief analysis were also given.It shows that many strain accumulation signals recorded by 6 strainmeter net... |
