To accurately estimate a depth of a hard bedrock by utilizing ground information from multiple locations.SOLUTION: A ground estimation method for estimating a depth of a hard bedrock below a ground surface comprises: a first shear wave velocity identification step of obtaining a first shear wave velocity Vs1 that is a shear wave velocity at a first point; a second shear wave velocity identification step of obtaining a second shear wave velocity Vs2 that is a shear wave velocity at a second point; a third shear wave velocity estimation step of estimating a third shear wave velocity Vs3 that is a shear wave velocity at a third point in which the depth of the hard bedrock is not investigated from the first shear wave velocity and the second shear wave velocity. When a predominant frequency at the third point is f3, a depth H3 of the hard bedrock at the third point is calculated using H3=Vs3/(4×f3).SELECTED DRAWING: Figure 2
