Understanding Earth Pressure Coefficient Calculator
Calculating the Earth Pressure Coefficient is crucial in civil engineering, especially when designing structures like retaining walls. This coefficient helps engineers determine the lateral pressure exerted by soil against a retaining wall. Let’s delve into the formula and its components.
Cohesion
Cohesion is the internal molecular attraction that holds soil particles together. In our calculator, it represents the cohesive strength of the soil.
Angle of Internal Friction
The angle of internal friction is the angle at which soil particles resist movement against each other. It’s a critical parameter reflecting the soil’s shear strength.
Density of Soil
Density refers to the mass per unit volume of the soil. It plays a significant role in determining the lateral earth pressure.
Height of Retaining Wall
The height of the retaining wall is the vertical distance from the base to the top of the wall. It directly affects the lateral forces exerted by the soil.
Earth Pressure Coefficient Formula
The formula used in our calculator is based on the Rankine Earth Pressure theory. The coefficient (K) is calculated using the following formula:
