Box Culvert Design Calculations Eurocode 2021 [work] -

For scenarios where groundwater tables can rise above the structure, the total stabilizing permanent self-weight must counteract buoyancy forces with an appropriate safety factor.

The culvert must withstand a complex combination of vertical and horizontal forces. 3.1. Permanent Loads (Dead Loads) Density of reinforced concrete (≈ 25 kN/m³). Earth Load (EV): Vertical pressure from fill, calculated as γsgamma sub s is soil density (≈ 18-20 kN/m³) and is fill height. Asphalt/Pavement Load ( Gacap G sub a ): Surfacing material on top. 3.2.
