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

Process Integration

This skill integrates with:

• Retaining Wall Design
• Foundation Design
