徐州台体积式应变仪和弦频式钻孔应变仪观测资料的对比分析

摘要: 本文从理论上推导了处于同一地点的体积式应变仪与弦频式钻孔应变仪测值之间的关系。进而对徐州台安装在同一个山洞、不同钻孔内的体积式应变仪和弦频式钻孔应变仪的实测值进行了相关分折。结果表明,二者相关性很好,与理论计算的结果基本一致。最后,对造成两者比例因子差异的原因进行了简略分析。Abstract: In this paper, the relations between observation data of the cobie-strai nmeter and string-frequency borehole stainmeter installed in the same position have been theoretically infered. Then, for the actual observation data obtained by two types of strainmeters in Jiangsu province, we made a correlation analysis. The results show a good correlation betwen them, and are consistent with the theoretical calculation results. Finally, the causes of the difference between the theoretical and actual proportional factors have been discussed.
