CRITERIA FOR THE DESIGN OF SAFE SLOPING CULVERT GRATES

USING A MATHEMATICAL COMPUTER SIMULATION TECHNIQUE, THIS STUDY INVESTIGATED THE DYNAMIC BEHAVIOR OF A SELECTED AUTOMOBILE NEGOTIATING A 50' WIDE MEDIAN CONTAINING A CROSS-OVER WITH A LONGITUDINALLY SLOPING CULVERT GRATE INLET. TWENTY-THREE COMPUTER RUNS WERE MADE AND IT WAS DETERMINED THAT 8:1 DITCH SIDE SLOPES AND 10:1 CULVERT GRADE SLOPES PRODUCED TOLERABLE ACCELERATIONS IN THE VEHICLE. STEEPER COMBINATIONS OF MEDIAN DITCH SIDE SLOPES AND CULVERT GRADE SLOPES WERE FOUND TO PRODUCE SEVERE ACCELERATIONS AND/OR ROLL OVER AND SHOULD NOT BE USED. /AUTHOR/
