FOUNDATION ANCHOR PILES IN CLAY-SHALES

EARTH DAMS AND APPURTENANT STRUCTURES IN THE PRAIRIE PROVINCES ARE OFTEN CONSTRUCTED ON A CLAY-SHALE FOUNDATION. CONCRETE STRUCTURES SUCH AS SPILLWAYS MAY BE DAMAGED DUE TO SWELLING OF THE FOUNDATION OR TO DIFFERENTIAL MOVEMENTS. VARIOUS PROTECTIVE DEVICES HAVE BEEN INSTALLED TO REDUCE AND CONTROL THE AMOUNT OF SWELLING AND DIFFERENTIAL HEAVE BENEATH STRUCTURES. HOLD DOWN PILES, OF REINFORCED CONCRETE WITH FLARED BOTTOM OFTEN BECAME INEFFECTIVE THROUGH BREAKAGE OR SLIPPAGE. ANCHOR PILES WERE DESIGNED TO STRETCH A CERTAIN EXTENT WITHOUT FAILURE DUE TO LOAD APPLIED DUE TO SWELLING OF THE SHALE. IT IS HOPED THAT THIS TYPE WOULD REDUCE THE AMOUNT AND RATE OF SWELLING AND DIFFERENTIAL MOVEMENT. THE DESIGN INCLUDES RECOMMENDATIONS FOR DEPTH OF ANCHORING, PILE SPACING AND SIZE OF ANCHOR ROD FOR VARIOUS BELL SIZES. /CGRA/
