The influence of nonvanishing of channel consistence moveout upon observation precision in the course of Rayleign wave exploration is discussed in this paper. Moreover, the bearing capacity including complex foundation bearing capacity in production, which is generally difficult to determine, is analysed and its determination is given. On the basis of the test results with static Rayleign, the paper illustracts the effectiveness of the method proposed by the author in solving problems. The method also contributes to the improvement of exploration precision.
