Abstract
A monitoring device (14) for a continuous flight auger is connected between a continuous flight auger (11) and a drive mechanism (12) and rotates with the auger. A strain measurement arrangement provides strain signals for use in deriving the rotational torque and axial force of the auger. The axial strain and rotational torque information are used to build up a model of the ground. In particular, the shear strength of the soil can be determined which enables the maximum pile capacity to be calculated without a detailed site investigation.
