位移观测值协方差矩阵模拟及其在整体解算地壳应变场中的应用

IMITATING COVARIANCE MATRIX OF DISPLACEMENT DATA AND ITS APPLICATION IN CALCULATION OF CRUSTAL STRAIN FIELD AS A WHOLE

摘要:

借助高斯型函数模拟分散分布的不同监测网点位移观测值的协方差矩阵,并将其应用于广东新丰江地区地壳应变场的计算中.结果表明:本文的方法不仅计算简便,模拟效果及计算稳定性较好,而且对联系分散分布的单元有一定的意义.

Abstract:

Using the Gauss-type function, covariance matrix of displacement data of different monitoring nets which have a scattered distribution is imitated. Moreover, the method is applied in calculation of crustal strain field of Xinfengjiang area, Guangdong province. The results show that the method not only is simple, effective and stable, but also has a certain meaning in relating the scattered elements.
