EN 1997 Part 1 establishes the general basis for geotechnical aspects of design, including the calculation of earth pressures, ground water pressures, bearing resistance, and foundation stability. box culvert design calculations eurocode 2021

The design of a reinforced concrete box culvert under Eurocodes (specifically for loading and

The design process for a reinforced concrete box culvert comprises a systematic structural analysis for bending moments, shear forces, and axial forces due to various loading conditions. for structural design) follows a rigid structural report

For top slab under traffic: Allowable span/effective depth ratio is ≤ 20 for simply supported, ≤ 25 for continuous (preliminary). For a 3m span (continuous) → d ≥ 3000/25 = 120 mm, easily satisfied by typical 300 mm slab.

Since $K < K_bal (\approx 0.167)$, compression reinforcement is not required.
