The stiffness of particulate media and the velocity of wave propagation are determined by the state of stress. Therefore, boundary measurements of travel time can be inverted to determine the field of velocity and converted to image the state of stress. Results from a simulation study are presented for the cases of footings and tunnels. The underlying assumptions in the simulation are highlighted and difficulties in field implementations are discussed.
