Pile Capacity Designer — Ebora

🛢️ Pile Capacity Designer

Axial capacity of a single driven or bored pile in layered soil — skin friction (α-method in clay, β-method in sand), end bearing (9·cᵤ in clay, σ′ᵥ·N_q in sand), with the effective- stress profile and water table. Get Q_ult & the allowable load Q_all (FS), an optional pile-group check, a soil-profile diagram, full worked steps, and a PDF report.

Factor of safety FS

Pile head at ground surface. L is measured from the surface to the pile tip. Use γ above the water table and γ′ = γ_sat − 9.81 below it.

⚠️ A teaching tool. N_q, α, β, K and δ depend on soil type, installation and your course's chart/method — confirm values against your references and the governing code (NSCP / DPWH). Verify before any real design.
