摘要
Abstract
The YRY-4 component borehole strain gauge has the characteristics of high resolution and can record various types of external interference in actual operation processes,which is manifested as sudden changes or abnormal trends of observation curves.This study selects and analyzes the observation data of five sets of four component borehole strain gauges in the Xinzhou area,Shanxi Province since their operation,based on the characteristics of various interference factors.The results show that in daily operation,typical interference factors affecting borehole strain observation mainly include observation systems,natural environments,field environments,human interference,etc.The observation systems are stable and have good seismic reflection efficiency.关键词
