| The Study of Crosshole Seismic Tomography in the Investigation of Geological Hazards |
| The crosshole seismic tomography for geological hazardous bodies belongs to nonlinear tomography for complicated models or high contrast velocity models. In order to provide a wavelet transform based multiscale inverse method of seismic tomography,this paper has for the first time introduced the wavelet multi scale to the seismic tomography,thus effectively solving the difficulty of nonlinear tomography and enhancing the tomographic resolution.The practicability and good effect of the method have been proved by the numerical modeling and some real cases. |
