GROUND DETERMINATION SUPPORT METHOD, GROUND DETERMINATION SUPPORT SYSTEM, AND GROUND DETERMINATION SUPPORT PROGRAM
To provide a ground determination support method, a ground determination support system, and a ground determination support program for precisely determining whether or not the ground is hard using a specific threshold.SOLUTION: A ground hardness determination system 30 is provided with a construction index value storage unit 33 for storing a construction index value based on an excavation measured value acquired when excavating a hole in the ground, and a control unit 31. The control unit 31 identifies a first identifier determining whether or not the ground is hard based on a N value of depth and a soil property. The control unit 31 identifies threshold candidates on objective construction indexes used for determination of ground hardness, compares each value of the objective construction indexes with the threshold candidates, so as to identify a second identifier determining whether or not the ground is hard at the depth at which each value of the objective construction indexes is acquired. The control unit 31 calculates, while changing the threshold candidates, a capturing rate and an error detection rate using the number of data of the objective construction indexes categorized based on the first identifier and the second identifier, and uses them to determine the threshold value on the objective construction index.SELECTED DRAWING: Figure 2
【課題】特定した閾値を用いて、地盤が固いか否かを的確に判定するための地盤判定支援方法、地盤判定支援システム及び地盤判定支援プログラムを提供する。【解決手段】地盤固さ判定システム３０は、地盤に孔を掘削するときに取得した掘削計測値に基づく施工指標値を記憶した施工指標値記憶部３３と制御部３１とを備える。制御部３１は、深さのＮ値及び土質に基づいて地盤が固いか否かを判定した第１識別子を特定する。制御部３１は、地盤の固さの判定に用いる対象施工指標についての閾値候補を特定し、対象施工指標の各値と閾値候補とを比較した結果、この対象施工指標の各値を取得した深さにおける地盤が固いか否かを判定した第２識別子を特定する。制御部３１は、閾値候補を変更しながら、第１識別子及び第２識別子に基づいて分類される対象施工指標のデータ数を用いて、捕捉率及び誤検出率を算出し、これらを用いて対象施工指標についての閾値を決定する。【選択図】図２
