Abstract

This paper descriptionbes the data obtained from the instruments placed in the Bridle Drift embankment to measure settlements and pore pressures. Internal settlement data have made possible the evaluation of the compressibility of the dolerite rockfill and comparisons are made with similar data from several overseas dams. A longitudinal crest crack resulting from differential settlement between the upstream shell and the remainder of the fill is discussed. Piezometer data obtained in the decomposed shale core both during and after construction are evaluated with reference to similar data from two other South African dams.
