a5c-ai 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
