怀来台体应变干扰因素分析及质量评价
Interference Factors and Quality Evaluation of Volumetric Strain Gauge at Huailai Seismic Station
【摘要】 以怀来台TJ-Ⅱ型钻孔体应变仪为研究对象,通过对2018年至2020年观测资料的质量进行分析,结果发现体应变观测资料完整率及内在精度符合观测规范技术要求,影响观测质量的因素主要有自然环境、电源干扰、人为干扰和钻孔地质条件,同时发现怀来台体应变观测与钻孔气压呈正相关,与钻孔水位呈负相关。
【Abstract】 Taking TJ-Ⅱ bore-hole volumetric strain gauge at the Huailai seismic station as a research object,we analyzed the quality of observation data from 2018 to 2020.The results show that the integrity rate and intrinsic accuracy of the bore-hole volumetric strain gauge observation data meet the technical requirements of the observation.The main factors affecting the observation quality are natural environment,power interference,human interference and borehole geological conditions.We found that the bore-hole volumetric strain observation at the Huailai seismic station is positively correlated with the borehole pressure,whereas negatively correlated with the borehole water level.
