%X Crosshole seismic tomography in complex media is a very complicated nonlinear inverse problem. It is difficult to obtain a satisfactory and clear image by using linearized tomographic method. This paper proposes a wavelet transform based on multi-scale inverse method of seismic travel-time tomography using the forwarding method of the graph based on bending ray tracing. This method effectively solves the difficulty of nonlinear tomography, overcomes the drawbacks of the linearized inverse methods and enhances the tomographic resolution. The results of physical modeling show that the method is high resolution, suitable to complicated models and good effect.
