Abstract
A ground anchorage testing arrangement having an impulse imparting apparatus connectable to a ground anchorage tendon ( ) or element thereof to be tested, the impulse imparting apparatus comprising an attachment means ( ) for attachment to the ground anchorage tendon ( ), a movable mass ( ), a guide ( ) for guiding movement of the mass in the direction substantially aligned with the axis of the ground anchorage to be tested and a drive means for imparting a driving force to move the mass in said direction (not shown). A method of assessing the integrity of ground anchorages, the method comprising the steps of (a) imparting a load impulse to a ground anchorage tendon to be tested, (b) monitoring the vibrational response signal of the anchorage to the imparted load impulse, (c) conditioning the vibrational response signal and (d) applying the conditioned vibrational response signal to an artificial neural network.
