Experimental and numerical investigation of a deep-corrugated steel, box-type culvert
A comprehensive investigation of the behavior of a corrugated steel, box-type culvert is described. The culvert design is unique in its use of a deep-corrugated cross section (5.5 inch depth) and a welded corner connection to form a culvert span of 15 feet with a rise of less than 5 feet. A full scale field test was undertaken to measure the response of the culvert under construction and service loads at a highway installation. Extensive instrumentation that measured deformations and forces was installed on the culvert before it was backfilled. Data was acquired at frequent stages during construction of the sand fill and under the influence of a stationary truck with three loads at five locations on the completed roadway. Construction procedures that nearly overstressed the culvert are discussed. A numerical simulation of the construction and service loads on the soil- structure system was undertaken using the finite element code CANDE. To reduce numerical error associated with soil modelling, the sand used to backfill the culvert was tested extensively utilizing a cubical multiaxial testing device. Parameters for a hyperbolic soil model were derived with special provisions to model the soil along non-triaxial compression stress paths. The numerical simulations are compared with the measured field response.
