Study of Box Culvert using Finite Element Method

Culverts are required to be provided under earth embankment for crossing of water course like streams, Nallas etc. across the embankment, as road embankment cannot be allowed to obstruct the natural water way. The culverts are also required to balance the flood water on both sides of earth embankment to reduce the flood level on one side of road thereby decreasing the water head consequently reducing the flood menace, Box Culverts are ideally suitable monolithic structures across a highway or railway embankment to balance the flood water on both sides. It consists of top slab, bottom slab and two vertical side walls. It is most economical due to monolithic action and no separate foundation required since bottom slab serves as a mat foundation. The present study, an attempt is made to combine and study the effects of those parameters for live load. To perform a parametric study of the RCC box culvert with varying depth of cushion, coefficient of earth pressure and angle of dispersion for live loads. To compare results calculated by using IS code method with Software based on Finite Element Analysis, Depth of cushion, coefficient of earth pressure for lateral pressures on walls, width or angle of dispersion for live loads on box without cushion and with cushion for structural deformations are important.
