MEASUREMENTS OF EARTH PRESSURES ON CONCRETE BOX CULVERTS UNDER HIGHWAY EMBANKMENTS

Two sections of a new culvert were instrumented to obtain a better understanding of the stresses acting on cast-in-place concrete box culverts, and also to investigate the conditions that result in a culvert failure under 12 meters of backfill. The measured earth pressure distribution was found to depend on the height of the embankment over the culvert. For low embankment heights, the average measured vertical earth pressures, weighted by tributary length, were about 30% greater than the recommended AASHTO pressures; the measured lateral pressures were slightly greater than AASHTO pressures. As embankment height increased, the measured weighted average vertical stress exceeded the AASHTO pressures by about 20%. Lateral pressures which exceeded the vertical pressures were recorded at the bottom of the culvert walls, and small lateral pressures were recorded on the upper locations of the wall. The high lateral pressures at the base of the wall are consistent with results from finite element analyses with high density backfill material placed around the culvert.
