ii) BD 31/01 The Design of Buried Concrete Box and Portal Frame Structures
iii) MS 1293 : Part 1 : 1992
- Box culverts are able to withstand a standard 2m (Max.) of superimposed backfill depth and 45 units of HB vehicle live load.
- Standard size box culverts also comply with proof load test of 112.5 kN over an area of 320mm x 320mm placed at any position on the box culvert's lid.
- Minimum backfill depth of 600mm over box culverts are recommended to avoid undesirable direct impact load.
- Hydrostatic pressure is eliminated by provision of weepholes placed along the centerline of the invert wall.
