Retaining Wall Earth Pressure Calculator
Calculate lateral earth pressure on retaining walls for different soil conditions and wall types. Get accurate results for active, passive, and at-rest pressures.
Frequently Asked Questions
What is lateral earth pressure?
Lateral earth pressure is the pressure that soil exerts horizontally against structures like retaining walls. It depends on soil properties, wall movement, and external loads.
What’s the difference between active and passive pressure?
Active pressure occurs when a wall moves away from the soil mass (minimum pressure), while passive pressure develops when the wall moves into the soil (maximum resistance).
How does water table affect earth pressure?
A high water table increases lateral pressure due to hydrostatic pressure and reduces soil strength. Proper drainage is crucial for retaining wall stability.
