By using the Corresponding Principle in the theory of rheologic mechanics, we derived the analytic expressions of viscoelastic displacement, normal strains, the shear strains， bulk-strain, the ground tilt , the increment of underground water level, the variation the of resistivity at an arbitrary point (x,y,z) in three directions of X-axis, Y-axis and Z-axis produced by a three-dimensional inclusion in the semi-infinite rheologic medium defined by the standard linear rheologic model. After the spatial-temporal variation of bulk-strain being computed on the ground produced by such a spherical rheologic inclusion, some interesting results are obtained, suggesting that the bulk-strain produced by a hard inclusion change with time according to three stages (α,β,γ) with different characteristics, similar to that of geodetic deformation observations, but different with the results of a soft inclusion. These theoretical results can be used to explain the characteristics of spatial-temporal evolution, patterns, quadrant-distribution of earthquake precursors, the changeability, spontaneity and complexity of short-term and imminent-term precursors. It offers a theoretical base to build physical models for earthquake precursors and to predict the earthquakes.
