WORKS CARRIED OUT IN ANHYDRITE AND GYPSUM DEPOSITS /SPANISH/

THE PAPER DESCRIBES THE CONDITIONS UNDER WHICH THE HEADWATER TUNNELS FOR TWO HYDROELECTRIC PLANTS IN ALGERIA WERE CONSTRUCTED THROUGH EXTENSIVE GYPSUM AND ANHYDRITE DEPOSITS. THE RENFORCEMENT OF THE TUNNEL WALLS WITH AN EXTRA LAYER OF CONCRETE IS DESCRIBED TOGETHER WITH THEIR WATERPROOFING; A HIGH-QUALITY CALCIUM SULPHATE RESISTANT CEMENT WAS USED. DETAILS ARE GIVEN OF SOM LABORATORY TESTS ON THE TRANSFORMATION OF ANHYDRID INTO GYPSUM. THE CALCULATION OF TUNNEL SURFACINGS IN SOIL BONTAINING SULPHATE IS BASED ON THE RESULTS OF THOSE TESTS. /LCPC/RRL/
