The invention discloses a multi-grid Chebyshev parallel spectral element method. The method includes the steps that a, a calculation area is divided into large and regular units; b, main grids and auxiliary grids are defined in the units, and the main grids are Chebyshev collocation points; c, Wave fields in the units are subjected to Chebyshev truncation expansion by the utilization of the main grids, and medium parameters and external forces in the units are subjected to truncation expansion by the utilization of the auxiliary grids; d, wave field, medium parameter and external force truncation expansion formulas are substituted into a wave equation to obtain unit mass matrixes, unit stiffness matrixes and unit external force vectors; e, on the basis of the unit mass matrixes, the unit stiffness matrixes and the unit external force vectors, an elastic wave expansion is solved on the main grids.
