EXPERIENCE AND RESEARCH WITH ASBESTOS-CEMENT PIPES BURIED IN VICTORIAN CLAYS

IN SOME OF THE EXPANSIVE-CLAY AREAS OF VICTORIA, AUSTRALIA, THE LOCAL STATE RIVERS AND WATER SUPPLY COMMISSION FINDS OCCASIONAL TRANSVERSE FAILURES OF ASBESTOS- CEMENT PIPES, MAINLY IN THE LATE SUMMER OR EARLY AUTUMN. TO OVERCOME THESE FAILURES, THE COMMISSION UNDERTOOK A RESEARCH PROGRAM BASED ON AN INITIAL STUDY OF THE BREAKAGE RECORDS FOR MOST TOWNS IN VICTORIA. THIS PAPER ATTEMPTS TO DESCRIBE THE PROGRAM AND EXAMINE THE GENERAL RESULTS. THE STUDY INDICATES THAT THE FAILURE MECHANISM, RESPONSIBLE FOR THE BREAKAGE, RESULTS FROM UNEVEN LONGITUDINAL BENDING DUE TO DIFFERENTIAL SWELLING OF THE SOIL SURROUNDING THE PIPES. METHODS OF ALLOWING FOR, OR REDUCING THESE EFFECTS ARE INDICATED. /RRL/A/
