CULVERT ELONGATIONS IN FILLS FOUNDED ON SOFT CLAYS

THE RESULTS OF FIELD OBSERVATIONS OF A CULVERT ELONGATION UNDER A COMPLETED STABLE FILL ARE PRESENTED. THE MEASUREMENT OF CULVERT ELONGATION ON THIS AND SEVERAL OTHER STABLE FILLS OF SIMILAR DIMENSIONS ON THE SAME FOUNDATION MATERIAL SHOWED VERY LARGE MOVEMENTS. THIS ELONGATION APPEARED TO TAKE PLACE AS AN "ELASTIC" BULGING OF THE FILL DURING CONSTRUCTION. CONTINUOUS MEASUREMENTS OF CULVERT ELONGATION ARE NOW BEING USED TO CONTROL FURTHER FILLS BUILT ON SIMILAR FOUNDATIONS. IT IS CONSIDERED THAT ANY FAILURE COULD BE ANTICIPATED BY AN INCREASED RATE OF CULVERT ELONGATION. /CGRA/
