利用最小二乘配置识别西秦岭构造区跨断层水准形变异常应用的研究
Application of Least Square Collocation in Identifying Anomaly Deformation Curves of Cross-fault Leveling in Western Qinling Tectonic Area

将最小二乘配置方法的高斯型经验协方差函数模型应用于区域跨断层形变特征曲线的异常辅助识别。通过西秦岭跨断层形变区域水准对岷县-漳县6.6级、景泰5.9级地震等前兆异常判定算例，说明最小二乘配置内插拟合可以进行区域跨段层水准形变曲线的趋势模拟和辅助查找区间异常特征，对于跨断层形变曲线异常识别有一定意义。
The Gauss-Function Model,based on least square collocation,is used in anomaly assisted identification of the regional cross-fault deformation characteristic curves. The precursory anomaly judgment examples of regional deformation of cross-fault leveling in Minxian MS6.6, Jingtai MS5.9 and other earthquakes show that least square collocation can be fitted in regional cross-fault leveling deformation and helped identifying anomaly characteristics. The method has certain significance for the cross-fault leveling deformation identification.
