B2

To provide a foundation physical property estimation system which can practically accurately estimate foundation physical properties, even when existing data such as boring data is restricted in the periphery of an estimation point and it is difficult to accurately estimate a geologic structure including horizontal distribution.SOLUTION: A foundation physical property estimation system determines distribution probability of geology by boring data for an estimation point, and indicator kriging using a parameter serial deciding method for a standard geology classification used in estimation. The system determines whether or not an estimation range of a physical property value is local to the distribution probability of the geology, and calculates a distribution probability-weighted average, a correction distribution probability-weighted average, or a logarithm distribution probability-weighted average according to the result to obtain a peculiar physical property value of the standard geology classification. The system determines reproducibility of test data of the peculiar physical property value, defines the peculiar physical property value as a foundation physical property value if the reproducibility is good and defines optimal geology classification and a peculiar physical property value by a step intersection verification method, and defines the peculiar physical property value as a foundation physical property value if the reproducibility is poor.SELECTED DRAWING: Figure 1
