FAILURE CHARACTERISTICS OF AN ARCH PLATE CULVERT. FINAL REPORT

An existing 37 year old, 15.67 ft span, 9.58 ft rise structural plate pipe arch culvert installed in cohesive backfill material was instrumented with biaxial electric strain gages and position transducers and loaded with two hydraulic cylinders, simulating live load from the rear axle of a vehicle. The loads were positioned above the crown point of the pipe and increased in increments until moderate degree of structural failure was observed. During each increment of load application, biaxial strains, deflections of the upper arc, and structural settlement were recorded. These field data were utilized to determine biaxial stresses, thrusts, bending moments, and geometrical change of the pipe. The field test conditions were also simulated numerically using the Culvert ANalysis and DEsign (CANDE) computer program, and results of the numerical analysis were compared with the field data. Based on the results of this investigation, failure mechanisms resulted from plastic bending rather than thrust, and despite being installed with a silty clay backfill and exhibiting severe metal deterioration, the pipe supported exceptionally large load.
