基于滑动方向拟合法的基本思想,国内外学者提出多种利用震源机制解数据反演构造应力张量的具体算法。本文在对其中的两种典型算法的原理思路进行介绍的基础上,着重分析了两种典型算法的特点和优点,以及不足之处。依据人工数值试验的一些初步结果,对两种典型算法有针对性地提出了相应的改进思路,以期为利用震源机制解数据反演构造应力张量算法的改进完善以及合理应用提供借鉴。
Based on the basic idea of sliding direction fitting method, many domestic and foreign scholars have proposed a variety of specific algorithms that use focal mechanism solution data inversion to construct the stress tensor. Based on introduction of the principle of two typical algorithms, this paper focuses on the analysis of the characteristics, advantages and disadvantages of the two typical algorithms. According to some preliminary results of artificial numerical experiments, some corresponding improvement ideas are put forward for the two typical algorithms in order to provide reference for the improvement and perfection of the stress tensor algorithm which is used to solve the data inversion by the focal mechanism.
