| 英文摘要 | The coseismic displacement, strain and stress, especially the change of the coseismic stress, are significant in the earthquake triggering investigation. Based on the layered elastic model, we develop a method to calculate the coseismic dislocation by the generalized reflection-transmission coefficient matrix and discrete wavenumber method. We can use it to calculate the coseismic strain, stress, and the change of Coulomb stress. It can be applied in the general situation. The receiver can be located on the surface or underground. The earthquake source can be pure shear dislocation source or tensile source. For the half-space model, the result of our method coincides with the analytical solution, so the precision of our method is reliable. The method can be used to calculate the Coulomb stress after an earthquake, and the change of Coulomb stress can give a reference to estimate the distribution of the aftershocks. We combine the trapezoidal integration method with the Filon integration method to calculate the coseismic displacement. It improves the speed of the calculation and there is no accuracy loss. It is useful for the inversion research based on the coseismic displacement. |
