SUPPORT LAYER REACHING DETERMINATION DEVICE AND SUPPORT LAYER REACHING DETERMINATION METHOD
To provide a support layer reaching determination device and a support layer reaching determination method capable of highly accurately determining whether a support layer has been reached.SOLUTION: A support layer reaching determination device 30 comprises: a data acquisition unit 32 that acquires drilling recording data composed of a maximum depth of drilling and a value related to drilling resistance of a drilling machine for each preset measurement depth; a memory 31a that stores design soil quality data indicating a relation between the depth and soil quality based on a result of ground survey; an N value estimation unit 35 that calculates an estimated N value by using an N value estimation model including the drilling recording data and the design soil quality data in input elements; and a soil quality estimation unit 36 that estimates the soil quality by using a soil quality estimation model including the drilling recording data and the estimated N value in input elements.SELECTED DRAWING: Figure 3
【課題】支持層に到達したか否かを高い精度で判定することができる支持層到達判定装置および支持層到達判定方法を提供する。【解決手段】支持層到達判定装置３０は、予め設定した計測深度ごとに、掘削の最大深度と掘削機の掘削抵抗に関する値とで構成された掘削記録データを取得するデータ取得部３２と、地盤調査の結果に基づく深度と土質との関係を示す設計土質データを記憶するメモリ３１ａと、掘削記録データと設計土質データとを入力要素に含むＮ値推定モデルを用いて推定Ｎ値を算出するＮ値推定部３５と、掘削記録データと推定Ｎ値とを入力要素に含む土質推定モデルを用いて土質を推定する土質推定部３６と、を備える。【選択図】図３
