GROUND STRENGTH ESTIMATION METHOD AND SYSTEM
To provide a ground strength estimation method and system which can more simply and quickly estimate strengths of various object grounds on the land and in the water.SOLUTION: A ground strength estimation method estimates a strength of an object ground G by using a push-in amount to the object ground G calculated on the basis of a vertical displacement amount of a boom tip part 6c by rotation around a rear end rotation central part 6b when a boom 6 of a hydraulic heavy machine 2 is rotated downward around the rear end rotation central part 6b of the boom 6 and the object ground G is pressed by an attachment 10, and a vertical displacement amount of the rear end rotation central part 6b by rotation around a grounding fulcrum of a chassis 3 caused by a reaction force of the pressing force.SELECTED DRAWING: Figure 3
【課題】陸上や水中などの様々な対象地盤の強度を、一段と簡便かつ迅速に推定することができる地盤強度の推定方法およびシステムを提供する。【解決手段】油圧重機２のブーム６をブーム６の後端部回転中心部６ｂを中心に下方回転させてアタッチメント１０により対象地盤Ｇを押圧した時の後端部回転中心部６ｂを中心にした回転によるブーム先端部６ｃの上下変位量と、押圧の反力に起因する車台３の接地支点を中心した回転による後端部回転中心部６ｂの上下変位量とに基づいて算出した対象地盤Ｇへの押込み量を用いて、対象地盤Ｇの強度を推定する。【選択図】図３
