GROUND HARDNESS ESTIMATION SYSTEM AND GROUND HARDNESS ESTIMATION METHOD
To provide a ground hardness estimation system and a ground hardness estimation method that can efficiently evaluate the hardness of the ground.SOLUTION: A control unit 31 of a ground hardness estimation system 30 acquires values measured by a drilling depth measuring instrument 21, a flow rate measuring instrument 22, a current measuring instrument 23, and a vibration measuring instrument 24, and acquires a plurality of measured values from these values. The control unit 31 calculates a multiple regression equation by performing multivariate analysis using the acquired measured values and the hardness index value as explanatory variables and objective variables, and records them in a multiple regression equation storage unit 34. When the measured values for the excavation conditions of a hole to be evaluated are acquired, the control unit 31 estimates the hardness index value in the ground where the hole to be evaluated is excavated by using these measured values and the multiple regression equation.SELECTED DRAWING: Figure 2
【課題】地盤の固さを効率的に評価することができる地盤固さ推定システム及び地盤固さ推定方法を提供する。【解決手段】地盤固さ推定システム３０の制御部３１は、削孔深度計測器２１、流量計測器２２、電流計測器２３及び振動計測器２４において測定された値を取得し、この値から複数の計測値を取得する。制御部３１は、取得した計測値と固さ指標値とを、説明変数及び目的変数とした多変量解析を行なうことにより重回帰式を算出して、重回帰式記憶部３４に記録する。制御部３１は、評価対象の孔の掘削条件についての計測値を取得した場合、これら計測値と重回帰式とを用いて、評価対象の孔が掘削された地盤における固さ指標値を推定する。【選択図】図２
