Terzaghi's consolidation equation is a fundamental principle in soil mechanics that describes the time-dependent settlement of saturated soil layers under load. It integrates the concepts of effective stress, soil compressibility, and permeability to predict how quickly and how much a soil layer will compress.

Terzaghi's Consolidation Equation

Fundamental principle in soil mechanics

Time-dependent settlement refers to the gradual deformation or subsidence of soil or structures over time due to sustained loads, often influenced by factors like soil type, moisture content, and stress history. Understanding this phenomenon is crucial for predicting long-term structural stability and preventing potential failures in civil engineering projects.

Effective stress is a fundamental principle in soil mechanics that represents the stress carried by the soil skeleton, excluding pore water pressure, and it is crucial for understanding soil behavior under load. This concept is vital for analyzing soil stability, settlement, and strength in geotechnical engineering applications.

Effective Stress

Soil compressibility refers to the degree to which a soil mass decreases in volume under load, primarily due to the expulsion of water and air from its pores. It is a critical factor in geotechnical engineering as it affects settlement behavior and stability of structures built on or in the soil.

Soil Compressibility

Permeability is a measure of how easily a fluid can flow through a porous material, and it is a critical property in fields like geology, civil engineering, and materials science. It is influenced by factors such as the size and connectivity of the pores, the viscosity of the fluid, and the pressure gradient driving the flow.
