Primary Consolidation Calculator

Calculate excess pore pressure dissipation and settlement rate per Terzaghi theory. Drainage conditions (single/double). Rate of settlement at various times. Preloading and vertical drain design to accelerate consolidation.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.
