To provide a permeability test evaluation system and a permeability test evaluation method capable of estimating a hydrogeological structure with high accuracy from the result of a cross hole permeability test executed in a homogenous base rock having complicated bleeding channels independently from an initial mode.
After the permeability test of a ground 39 is performed to acquire a head diffusion coefficient 63 between observation points, the constellation 41 of observation points A, B to J is determined by using the inverse of the head diffusion coefficient 63 as similarity in a multi-dimensional scaling method. A point group 45 is arranged at uniform density within a polygon 44 having the constellation 41 of the observation points as an apex and a center of gravity matched to an origin, in which the square of the difference between the constellation 41 of the observation points and a position 46 in a real space of the observation points is minimized. Geometric reconstitution is performed by use of inverse distance interpolation so that the constellation 41 of the observation points is moved to the position 46 in the real space of the observation points, and the density of the point group 45 is measured for the real space, whereby a hydrogeological structure model is formed.
