FOUNDATION PHYSICAL PROPERTY ESTIMATION SYSTEM, FOUNDATION PHYSICAL PROPERTY ESTIMATION METHOD, THREE-DIMENSIONAL FOUNDATION INFORMATION ESTIMATION SYSTEM, THREE-DIMENSIONAL FOUNDATION INFORMATION ESTIMATION METHOD, PROGRAM, AND RECORDING MEDIUM
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
【課題】推定地点周辺において、ボーリングデータなどの既存データが限られ、水平分布も含む地質構造の確度の高い推定が困難な場合においても、地盤物性を実用上十分な精度で推定することができる地盤物性推定システムを提供する。【解決手段】地盤物性推定システムは、推定地点に関し、ボーリングデータと、推定に用いる標準地質区分とに対してパラメータ逐次決定法を用いたインディケータクリギングにより地質の分布確率を求める。地質の分布確率に対して物性値の推定範囲が局所的か否かを判断し、その結果に応じて、分布確率加重平均、補正分布確率加重平均または対数分布確率加重平均を取って標準地質区分の固有物性値とする。その固有物性値の試験データの再現性を判断し、再現性が良ければこの固有物性値を地盤物性値とし、再現性が不良であればステップ交差検証法により最適地質区分と固有物性値とを決定し、地盤物性値とする。【選択図】図１
