Performance of Soil Pressure on the Culvert under High-Backfill Reinforced with Geosynthetics

Abstract:

Finite element model of culvert under high-backfill reinforced with Geosynthetics was set up to calculate the soil pressures on culvert and the effects of load reduction by reinforcement were analyzed in the paper. Results showed that the soil load on culvert under embankment reinforced with geosynthetics was reduced significantly compared with the one under unreinforced embankment, the reduction effects were related with reinforcement layers and space. With increasing layers the soil load reduced, but the amount of reduction seemed out of proportion to the layer increasing, to some extent the layers will contributed only a little to the load reduction. Comparatively, the reduction effects enhanced remarkably with space of reinforcement. Results will benefit to design and construction of engineering.
