Factor of safety

Terzaghi's equation predicts the ultimate bearing capacity of a shallow footing as the sum of cohesion, surcharge, and self-weight terms, each with a bearing-capacity factor that grows sharply with the soil friction angle. Dividing by a factor of safety gives the allowable pressure. Educational tool, not a geotechnical design.

Governing equation

q_{u} = c N_{c} + γ D_{f} N_{q} + \frac{1}{2} γ B N_{γ} = 10 (30.1) + 27 (18.4) + \frac{1}{2} (18) (2) (22.4) = 1201 kPa

Reading this result: Mixed c-φ soil: all three terms contribute — deeper embedment and a wider footing both push the ultimate capacity higher.

Pumping rate Q (m³/day)

Transmissivity T (m²/day)

Radius of influence R (m)

Pumping a well lowers the water table into a cone of depression. Under the Thiem steady-state solution the drawdown is s(r) = Q/(2πT)·ln(R/r): more pumping deepens the cone, higher transmissivity flattens it. Fundamental to well design, water supply, and contaminant capture.

▶ Run in Python

Drawdown at well4.7 m

Drawdown at 50 m1.47 m

Radius of influence500 m

Governing equation

s (r) = \frac{Q}{2 π T} ln \frac{R}{r} = \frac{2000}{2 π \cdot 500} ln \frac{500}{r}

Reading this result: Drawdown is Q/(2πT)·ln(R/r): here it is about 4.7 m at the well and falls off logarithmically, so most of the depression sits in the first tens of metres.
