用边长变化结果计算地应变及块体划分

在均匀应变的假设下 ,给出了由边长变化求解地应变的新方法 ,通过统计检验相邻三角形的最大主应变 ,可判别相邻测点是否位于同一个均匀应变块体上。采用弹性位错理论设计的模拟算例表明 ,该方法能成功地将位于断层两侧的测量点分辨开。||In this paper a method is proposed for calculating strains based on baseline length changes. A statistical test of strains of adjacent triangles is formulated to determine whether the adjacent measure points are located on the same tectonic blocks. By using the dislocation model, a simulated example is designed and shows that the proposed method can divide the measure points into different tectonic blocks successfully.
