     with the aid of a method of displacement potentials, an efficient and accurate analytical derivation of the three-dimensional dynamic green’s functions for a transversely isotropic multilayered half-space is presented. constituted by proper algebraic factorizations, a set of generalized transmission–reflection matrices and internal source fields that are free of any numerically unstable exponential terms are proposed for effective computations of the potential solution. three-dimensional point-load green’s functions for stresses and displacements are given, for the first time, in the complex-plane line-integral representations. the present formulations and solutions are analytically in exact agreement with the existing solutions given by pak and guzina (2002) for the isotropic case. for the numerical computation of the integrals, a robust and effective methodology which gives the necessary account of the presence of singularities including branch points and poles on the path of integration is laid out. a comparison with the existing numerical solutions for multilayered isotropic half-space is made to confirm the accuracy of the numerical solutions.
