摘要：
Considering the spherical visco-elastic structure, the post-seismic deformation inversion mode had been constructed based on the visco-elastic earth model. We developed the inversion mode and inversion software package based on the post-seismic fault dislocation model considering the crust-stratified structure. Using the genetic algorithm to invert the different fault dislocation parameters due to strike slip fault, dip slip fault respectively and comparing to the result inverted from the homogenous dislocation model, the result shows that the inversion algorithm used here could invert the dislocation parameters from the large region using the genetic algorithm and the inversion result is better to use. The inversion mode proposed here could better invert the seismic source parameters to different types fault. There is also a important find to suggest us that we could not use the minimum of VTPV as the only rule to judge the inversion result whether good or not when the model mode is not obvious. We should find other ways to make a supplement judge. ©, 2014, Wuhan University. All right reserved.
