STRENGTHENING OF MUDA DAM FOUNDATIONS USING CABLE ANCHORS

THE PRESENCE OF NEAR-HORIZONTAL MUDSTONE BANDS IN THE GENERALLY MASSIVE QUARTZITE MADE IT NECESSARY TO STRENGTHEN THE FOUNDATIONS OF MUDA DAM AGAINST SLIDING. RE-STRESSABLE CABLE ANCHORS, EACH LOADED TO 270 TONS, WERE ADOPTED FOR THIS PURPOSE. THE PAPER EXPLAINS THE BASIS OF THE CALCULATIONS FOR FOUNDATION STRENGTHENING, DESCRIBES THE INSTALLATION OF THE CABLE ANCHORS AND GIVES THE RESULTS OF SUBSEQUENT TESTS CARRIED OUT ON THEM BEFORE AND AFTER IMPOUNDING. /AUTHOR/
