000015250 520__ $$2eng$$aQuantitative evaluation of fluctuations of Lam´e constants in an elastic half-space is dealt in this paper. A near-field equation developed by Fata and Guzina[1] is modified via the Lippmann-Schwinger equation so that it expresses the relationship between the fluctuation of the wavefield and scattered waves. Since the near-field equation uses Green’s functions from the probing points as the scattered wavefields, evaluation of the fluctuation becomes also possible by means of the Green’s function from the probing points. As a result, an algorithm for the evaluation of the fluctuations is free from the limitation of the finite number of grid points of the observation surface, that was used to obtain the near-field operator. Several numerical calculations are carried out to examine the accuracy of the present method.
