Therefore an attempt is made to study the effects of cushion, co-efficient of earth pressure and angle of dispersion for live load. These affect the design significantly and therefore, required to be assessed correctly for designing a safe structure. A few things like depth of cushion, coefficients of earth pressure for lateral pressure on walls, width or angle of dispersion for live loads on box without cushion and with cushion for structural deformation are important items where opinion of the designers vary and need to be dealt in much detail. The method is well known and does not need any elucidation. The structure is designed like a rigid frame adopting moment distribution method for obtaining final distributed moments on the basis of the relative stiffness of the slab and vertical walls. For a box culvert, the top slab is required to withstand dead loads, live loads from moving traffic, earth pressure on sidewalls, water pressure from inside, and pressure on the bottom slab besides self weight of the slab. Sufficient length to accommodate the carriageway and the kerb. 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 items. This paper deals with study of some of the design parameters of box culverts like angle of dispersion or effective width of live load, effect of earth pressure and depth of cushion provided on top slab of box culverts. 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. across the embankment, as road embankment cannot be allowed to obstruct the natural water way. ABSTRACT : Culverts are required to be provided under earth embankment for crossing of water course like streams, Nallas etc. Professor, Civil Engineering Department, Saraswati College of Engineering, Maharashtra, India, 3 Lecturer, Civil Engineering Department, Saraswati College of Engineering, Maharashtra, India,
