Time Factor Consolidation Calculator
Terzaghi time factor Tv = cv * t / Hd^2, where cv is the coefficient of consolidation in m2/year, t the elapsed time since loading in years, and Hd the longest drainage path in m (half the layer thickness for double drainage).
Description
Terzaghi time factor Tv = cv * t / Hd^2, where cv is the coefficient of consolidation in m2/year, t the elapsed time since loading in years, and Hd the longest drainage path in m (half the layer thickness for double drainage).
Time Factor Consolidation Calculator: Terzaghi time factor Tv = cv * t / Hd^2, where cv is the coefficient of consolidation in m2/year, t the elapsed time since loading in years, and Hd the longest drainage path in m (half the layer thickness for double drainage).
When to use Time Factor Consolidation
Use this geological calculation for a transparent first-pass interpretation of measured rock, soil, fluid, well, stratigraphic, isotopic, geophysical, or seismic data under an explicitly selected model.
- cv
- Coefficient of consolidation cv in m2/year.
- t
- Elapsed time t in years.
- Hd
- Longest drainage path Hd in m.
How Time Factor Consolidation works
Terzaghi time factor Tv = cv * t / Hd^2, where cv is the coefficient of consolidation in m2/year, t the elapsed time since loading in years, and Hd the longest drainage path in m (half the layer thickness for double drainage). The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Tv
- Time factor Tv, dimensionless.
Limitations and assumptions
- Geotechnical correlations and idealized failure models depend on stratigraphy, sampling disturbance, drainage, stress history, groundwater, density, anisotropy, scale, construction sequence, and laboratory or field method. Site-specific design requires investigation and code factors.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Compare independent measurements and models, retain units and analytical metadata, propagate uncertainty, and validate interpretations against logs, cores, maps, laboratory data, or field observations.

Coefficient of consolidation cv = Tv * Hd^2 / t rearranged from the Terzaghi time factor, with Tv dimensionless, drainage path Hd in m and time t in years; result in m2/year.
- Secondary Compression Settlement Calculator
Secondary (creep) settlement Ss = H * C_alpha / (1 + e_p) * log10(t2 / t1), where C_alpha is the secondary compression index from the e - log10 t tail of an oedometer test, e_p the void ratio at end of primary consolidation, and t1, t2 the creep time window in years.
- Coefficient Of Volume Compressibility Calculator
Coefficient of volume compressibility mv = av / (1 + e0), where av = de / d_sigma' is the slope of the e - sigma' curve over a loading increment. Result in 1/kPa.
