【Abstract】 During the exploration,cavities within rock mass,dambody,tunnel and so on must be positioned.By the method of the corstic tomography technology, with the integral form of eihornal equation, through the process of discreteness,the map of elastic wave is found and,mathematical model is established. By the solution of SIRT algorithm,the position problem of the cavity is solved.更多还原
