This is a simple web app that is able provide a basic design of a cantilever retaining wall based on user inputs.

Main Features -

• Calculate earth pressure coefficients based on Rankine's theory and Coulomb's theory.
• Calculate Lateral earth pressure forces acting on the wall.
• Analysis of the wall to check various stability conditions and calculate Factor of safety.
• Calculate horizontal and vertical acceleration coefficients in accordance with Indian standard code IS:1893.
• Calculate seismic earth pressure coefficients in accordance with IS:1893, cl. 8.1.
• Perform seismic analysis using pseudo-static method of earth pressure analysis.
• Design of reinforcements for various elements of the wall.

• A perfectly granular backfill is considered for the analysis, which means there is no cohesion in backfill soil.
• Proper drainage is assumed to be provided by the designer so that no hydrostatic pressure is developed on the back of the wall.
• It is assumed that a triangular pressure distribution is developed on the back of the wall due to backfill earth.
• All earth pressure forces are considered to act on a vertical plane, which pass through the rear end of base slab.
• The wall inclination and friction angle between wall and backfill, are asumed zero for this plane while calculating the earth pressure coefficients.
