THE BORDAL EARTH-AND-ROCK FILL DAM

THE DESIGN, CONSTRUCTION, AND PERFORMANCE OF THE BORDAL DAM I ARE DESCRIBED. THIS DAM IS LOCATED IN THE MOUNTAIN REGIONS OF CENTRAL NORWAY AND IS PART OF THE TOKKE HYDRO- ELECTRIC PROJECT, COMPLETED IN 1959. THIS DAM WAS BUILT WITH A CENTRAL CORE OF MORAINIC MATERIAL, AND WITH A SUPPORTING FILL OF GRAVEL. A BRIEF REVIEW IS PRESENTED OF SITE INVESTIGATION, DESIGN, AND CONSTRUCTION OF THE DAM, TOGETHER WITH RESULTS OF THE LABORATORY TESTS PERFORMED DURING THE CONSTRUCTION. INSTRUMENTS WERE INSTALLED ON THE DAM TO MEASURE THE BEHAVIOR DURING CONSTRUCTION AND SUBSEQUENT OPERATION. THESE INSTRUMENTS CONSISTED OF PORE PRESSURE EQUIPMENT FOR INSTALLATION BOTH IN THE FILL AND IN THE ROCK FOUNDATION, AND OF THERMOELEMENTS FOR MEASURING TEMPERATURE INSIDE THE DAM. PRESSURE AND TEMPERATURE IN THE FILL, THE SETTLEMENTS ALONG THE CREST, AND THE LEAKAGE THROUGH THE DAM ARE MEASURED. PERFORMANCE MEASUREMENTS CARRIED OUT DURING THE FIRST YEARS AFTER THE DAM WAS COMPLETED INDICATE THAT LEAKAGE AND SETTLEMENTS ARE OF THE SAME ORDER OF MAGNITUDE AS PREDICTED.
