摘要：
Geotomography is widely used to interpret datas of underground structures. In this study seismic and electrical geotomography is tried to map underground cavity. In seismic geotomography, finite element method is used to calculate the first arrival time and LSQR(3)) inversion method is applied to calculate slowness matrix. In electrical inversion method, model experiment is conducted and experimental data are compared with that of theoretical inversion data And a new method for electric resistivity tomography(ERT) is developed for geophysical inverse problems by adapting the sensitivity analysis.
