计算断层自发破裂过程的离散网格划分研究

离散化网格的空间步长选取在各种数值算法中都是一个很受关注的问题，在全空间均匀介质模型和简单离散化方案下，利用边界积分方程方法研究在自发破裂求解过程中动力学参数组合Dc和Te (Dc为临界滑动弱化位移，Te为有效的断层破裂面上的初始应力)对计算网格划分的影响，初步得到了Dc和Te参数空间中的有效计算网格的选取规律，对合理、有效地运用边界积分方程方法计算地震震源的破裂过程具有重要的指导意义. 

Study on the meshing scheme in the computation of spontaneous fault rupture process

The choice of spatial grid size has been being a crucial issue in all kinds of numerical algorithms. As using BIEM(Boundary Integral Equation Method) to calculate the rupture process of a planar fault embedded in an isotropic and homogeneous full space with simple discretization scheme, this paper focuses on what grid size should be applied to control the error as well as to keep the computing efficiency for different parameter combinations of (Dc ,Te ), where Dc is the critical slip-weakening distance and ...
