Field instrumentation and testing of a functional cast-in-place reinforced concrete culvert in sarpy county, nebraska, are describedin this paper. The culvert is a double-cell box on a 35 deg skew. Each cell's inside dimensions are 12 ft by 12 ft. Permanent soil fillheight is 8.5 Ft. Construction began in november 1987 and ended in april 1988. Measurements of soil pressures, strains, deflections, and settlements were recorded both during and after construction. The soil pressures observed to date resulting from soil and truck loading are reported, and coparisons of measurements, theory, and aashto specifications are provided. This paper appears in transportation research record no. 1231, Analysis, design, and behavior of underground culverts.
