What is Retaining Wall Calculator?

▾

Konstrukce opěrné stěny odolává bočnímu tlaku půdy. Stabilita vyžaduje kontrolu klopného momentu, kluznosti a únosnosti.

How to Retaining Wall Calculator

▾

1Calculate lateral earth pressure: P = 0.5×γ×H²×K_a
2Check overturning moment ratio >1.5, sliding ratio >1.5, bearing pressure within limits
3Design wall geometry and reinforcement accordingly

Worked Examples

▾

Example 1

Given:H = 4 m, γ = 18 kN/m³, φ = 30°, wall width 1 m

Výsledek:Lateral force ≈ 48 kN/m, requires adequate base width

Stability checks needed

Real-World Applications

Troubleshooting and diagnosing electrical faults in real systems

Frequently Asked Questions

▾

Why do tall walls need wider bases?

Earth pressure increases with H²; larger base resists overturning moment created by lateral load.

How do drainage systems help?

Drainage behind wall prevents water buildup, reducing lateral pressure significantly.

Common Mistakes to Avoid

▾

!Neglecting water pressure on wall
!Under-sizing base relative to height

💡

Pro Tip

Never build a retaining wall without adequate drainage behind it — hydrostatic pressure from saturated soil is the leading cause of retaining wall failure.
