CALIFORNIA'S CULVERT RESEARCH PROGRAM--DESCRIPTION, CURRENT STATUS, AND OBSERVED PERIPHERAL PRESSURES

THE CALIFORNIA DIVISION OF HIGHWAYS IS PERFORMING AN EXTENSIVE RESEARCH PROGRAM TO DETERMINE STRUCTURAL BEHAVIOR OF BURIED CONDUITS. FIELD STUDIES INCLUDE OBSERVATIONS OF THREE ARCH CULVERTS, TWO RIGID CONCRETE PIPES, AND TWO FLEXIBLE (STRUCTURAL PLATE) PIPES. MEASUREMENTS INCLUDE PERIPHERAL AND EMBANKMENT PRESSURES, INTERNAL STRAINS, AND DISPLACEMENT FIELDS. PARAMETERS INCLUDE METHOD B (IMPERFECT DITCH) AND METHOD A (POSITIVE PROJECTION) BACKFILL, WELL GRADED AND POORLY GRADED STRUCTURE BACKFILL, AND, FOR THE PIPES, NUMEROUS BEDDING CONDITIONS. THEORETICAL STUDIES INCLUDE A FINITE ELEMENT ANALYSIS OF EMBANKMENT PRESSURES, TAKING INTO ACCOUNT SEQUENCE OF CONSTRUCTION OPERATIONS AND THE BALED STRAW LAYERS, AND NEUTRAL POINT ANALYSES OF ARCH CULVERT BEHAVIOR. A QUASI-THEORETICAL METHOD OF INFERRING SOIL PRESSURES FROM A CULVERT'S DISPLACEMENT FIELD HAS BEEN DEVELOPED. MODEL STUDIES FOR VERIFICATION ARE PLANNED. /AUTHOR/
