AbstractCrosshole tomography is usually carried out under the condition of isotropy. However, anisotropy exists in crust extensively. Considering the problem of aninsotrpic tomography has important theoretical and practical value. In the paper, based on the anisotropic traveltime disturbance theory, crosshole tomography by using qP- and qSV-wave traveltimes is studied. Compared with isotropic tomography, the anisotropic tomography is a more ill-posed problem. Here, combining regularization method and stastistical hypothesis testing theory, we proposed statistical crosshole tomography method and solve the problem effectively. Numerical results show the method has the advantages of ideal precision, stable calculation and less influence confined by initial models, moreover, it can be extended to solve other geophysical inverse problems.
