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

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.
