FIELD INVESTIGATION OF REINFORCED CONCRETE CULVERT PIPE
This report contains a description and analysis of a field investigation of a 5 ft 8 in by 6 ft 2 in elliptical concrete pipe culvert installed under a deep fill in a yard of one of the railroads in this country. The investigation was made to determine the strains in the reinforcement and pressure on the pipe as a fill of up to 40 ft was placed and for a period of nearly three years after filling was completed. On the basis of this investigation: 1) Strains from the load of the fill tend to become constant after a lapse of about two years after fill is placed. 2) The supporting strength of the pipe used in this installation was not sufficient for the type of bedding and backfill used. In the selection of a pipe proper attention must be given to the actual installation that the method of backfilling and bedding is consistent with the strength of pipe used.
