摘要
Based on data observed by YRY-4 4-component borehole strainmeters installed during the tenth five-year project of China, this paper makes a brief analysis of how atmospheric pressure, water level, and observation data are interrelated, and introduces some typical features of influences caused by water level interference. According to the analysis of data reliability, the authors focus on the distribution of response ratio, barometric coefficient, coefficient of water level and such inverse parameters, which are calculated by fitting data from highly-reliable observing stations using the comprehensive fitting model, during the period of equipment stability.
