新丰江形变网“真值”及其与地震关系的研究

THE RESEARCHES ON THE COMPUTING SYSTEM OF THE RELATIONSHIP BETWEEN THE "TRUTH VALUE" OF XINFENGJIANG DEFORMATI ON NETWORK AND EARTHQUAKE

利用新丰江３０年来连续完整的形变资料，进行了“真值”研究．从定量分析、精度评估和绝对位移等角度，建立了一套以＂真值＂研究为基础的，用统一、连续、定量可比尺度表示的稳定状态分析系统。结果表明，总体位移变化与地震活动关系密切并反映了水库地震的典型特征。文章对稳定状态分析系统的现实意义做了归纳，并总结出一组具有预报意义的定量辨识指标．

In this paper,using the continual measuring data of the deformation in Xifengjiang area in 30 years,the 'truth value' is researched,and based on that a series of analysis system of stable state has been established from quantitative analysis,accuracy evaluation and absolute displacement,this system is characterized by showing in a unified, continual, quantitative and compared scale.That indicated that there is close relationship between the variation of tatol displacement and seismicities,and it shows the typical characteristics of reservoir-induced earthquake.And the pratical significance of this analysis system of stable state was generalized,a series of quantitative identification norm with prediction significance has been summarized.
