One of aims for conducting shaker tests of a rigid bock is to obtain the experimental impedance functions for several modes, and to compare the theoretical functions which are reliable for the application to a design analysis of actual foundations. In this paper, three different kind of inverse methods for seeking the experimental impedance functions with coupled swaying and rocking modes of a rigid foundation are proposed. The methods apply to a case of the forced vibration test of a four-pile group with a reinforced concrete block at the cap, and then the resulting functions are compared with the theoretical ones obtained by the thin layer formulation which has given the well simulated results of the test. It is concluded that the inverse methods proposed are useful to evaluate the experimental impedance functions with coupled swaying and rocking modes on the basis of shaker tests of a rigid block.
