Earth Pressure Calculator Skill

Purpose

The Earth Pressure Calculator Skill determines lateral earth pressures on retaining structures using Rankine, Coulomb, and seismic methods for design of retaining walls and basement walls.

Capabilities

Active earth pressure (Rankine, Coulomb)
Passive earth pressure
At-rest earth pressure
Surcharge effects
Layered soil conditions
Seismic earth pressure (Mononobe-Okabe)
Sloping backfill effects
Water pressure considerations

Usage Guidelines

When to Use

Designing retaining walls
Analyzing basement walls
Evaluating excavation support
Assessing seismic pressures

Prerequisites

Soil parameters available
Wall geometry defined
Surcharge loads identified
Groundwater level known

Best Practices

Select appropriate theory
Consider wall movement
Include seismic where required
Account for drainage
