稳健基准应变分析法用于鲜水河断裂带活动特征研究

The Research on Active Characteristics of Xianshuihe Fault Based on Robust Datum Strain Analysis

摘要: 本文运用稳健估计法确定位移基准,以此为基础,识别影响均匀应变场的特殊位移信息,并在估计均匀应变参数的同时,也对特殊位移信息作出估计。用所提的分析方法对覆盖鲜水河断裂带的甘孜一塔公寺三角锁网三期成果进行了分析处理,研究了该断裂带的活动特征。

Abstract: In this paper, the datum of displacement is determined by means of robust estimation technique. Based on this datum, the special displacement information which impacts the homogeneous strain state is recognized and with the estimating the homogeneous strain parameters, the special displacement information is estimated as well. Furthermore, two periods data of triangulation chain in Ganzi-Tagong temple which covers xianshuihe fault are processed and the active characteristics in such zone are researched.
