Method for providing information related to the compaction state of a soil when performing a compaction operation with a soil compactor

摘要

A method for providing information related to the compaction state of a soil when performing a compaction operation with a soil compactor includes the measures:a) detecting a vertical acceleration and a horizontal acceleration of a vibrating roller when a soil compactor moves over a soil to be compacted;(b) establish a measurement relationship between a ground contact force (Fb) and a deflection (sw) of the vibration roller for a vibration cycle using the vertical acceleration and horizontal acceleration recorded in measure (a);c) Determine a simulation relationship (Zs) between the ground contact force (Fb) and the deflection (sw) for a vibration cycle using a soil model taking into account at least one simulation parameter;d) Comparison of the simulation relationship (Zs) with the measurement relationship,e) Determine that a preset value of at least one simulation parameter considered in the soil model substantially represents a corresponding soil parameter of the soil to be compacted if the simulation relationship (Zs) substantially corresponds to the measurement relationship.
