摘要
In a paper titled "The mechanism of long-distance jumping and the migration of main active areas for strong earthquakes occurred in the Chinese continent" (Vol.55, No.1 of Chinese J. Geophys. (Chinese Edition)), Yang et al. proposed to simulate the effects of earthquake fault slip by reducing shear modulus of the elements in calculation. Although this method can simulate the shear stress drop of a fault under compression and shear, it will produce a significant drop of normal stress on the fault which is incorrect. In this paper, we propose a better method—transverse isotropic "wounded element", and get a reasonable result, which is in good agreement with analytic solutions in the stress calculation as a result of fault slip.
