Kind Code:

B2

Abstract:

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
