FOUNDATION STUDIES IN GROUND WITH SUBTERRANEAN CAVITIES - PLACE OF GRAVIMETRIC METHODS

ETUDES DE FONDATION EN TERRAIN CAVERNEUX - PLACE DE LA GRAVIMETRIE

The role of geophysical investigations in foundation studies in ground containing cavities is examined, distinguishing between extensive cavities and small numerous holes. Microgravimetry is shown to be the only method able to directly detect the amount of tons of missing soil. Investigation by means of mechanical boreholes is not always easily interpreted, hence the usefulness of continuous recording of the drilling rate and reflected percussion. Various site investigation and foundation repair programmes are described. /TRRL/
