摘要
利用矩阵奇异值分解方法研究断层位错模型参数反演观测方程系数矩阵的奇异值的分布规律,探讨位移观测网相对于断层位置对反演断层位错模型参数结果的影响。模拟算例表明,位移观测网应布设在以断层为中心的周围,以提高反演解的稳定性。
Matrix singular value decomposition is used for studying the distribution of Singular Values of the observation equation coefficient matrix in inverting of fault dislocation parameters from measured displacement. The effect of relative position of surveying network to the fault on the inversion results has been studied. The results of simulative examples show that the surveying network should be distributed around the center of the fault monitored so as to improve the stability of inversion.
