Design of a trapezoidal retaining wall for cohesive soil

Quick answer：

The design of a trapezoidal retaining wall for cohesive soil involves calculating the necessary dimensions, materials, and reinforcement to ensure the wall's stability against the soil pressure. This includes determining the active and passive earth pressures, wall height, and soil properties. Engineers typically use the Rankine or Coulomb theories to calculate these pressures and ensure the wall's structural integrity.
