DESIGN OF CIRCULAR SOIL-CULVERT SYSTEMS

IN PREDICTING THE PERFORMANCE OF A SOIL-CONDUIT SYSTEM, SOIL PROPERTIES MUST BE INCLUDED IN THE DESIGN PROCEDURE. IT IS SUGGESTED THAT THE RELATION BETWEEN THE CONSTRAINED MODULUS OF ELASTICITY AND THE DRY DENSITY OF A SOIL AND THE SOLUTION FROM THEORY OF ELASTICITY CAN BE USED TO DEVELOP THE DESIRED DESIGN PROCEDURE FOR CIRCULAR FLEXIBLE PIPE. THE DESIGN CHART IS DEVELOPED BY USING THE SOLUTIONS DERIVED FROM THE THEORY OF ELASTICITY AND FROM THE RELATION BETWEEN CONSTRAINED MODULUS OF ELASTICITY AND DRY DENSITY. THE UPPER BOUNDARY OF THE DESIGN CHART WAS APPROXIMATED FROM THE FULL-SCALE EXPERIMENTAL RESULTS ON CORRUGATION PIPE AS REPORTED BY WATKINS AND MOSER. THE RING DEFLECTION OF 5 PERCENT WAS USED AS A LIMITING DEFORMATION OF PIPE. IT IS SHOWN THAT THE ACTUAL EXPERIMENTAL RESULTS OF WATKINS AND MOSER FALL IN THE RANGE OF VALUES OF A DIMENSIONLESS PARAMETER. TWO EXAMPLES ARE PRESENTED TO ILLUSTRATE THE USE OF THE DESIGN CHART.
