【摘要】 针对"十五"期间完成布设的YRY-4型四分量钻孔应变仪的观测数据,简要分析了气压、水位与应变观测三者间的相互影响关系,介绍了几种典型的水位干扰因素影响特点。在对观测资料进行初步评价的基础上,利用四分量观测特有的自检功能,对应变观测资料的质量进行了更深入的评价。依据资料质量评价结果,在仪器稳定期内借助包含气压、水位影响的综合拟合模型,给出了信度较高观测站的各路分量响应率、气压系数、水位系数等参数的分布情况,可作为今后进一步分析的背景参考。更多还原

【Abstract】 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.After the initial valuation of the data,we conduct a more thorough valuation on quality of the observed data by means of self-checking function specific to 4-component observation.According to the analysis of data reliability,we 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.This can provide a background reference for future analysis.更多还原
