Historical Perspective
The historical evolution of geotechnical engineering reflects humanity’s progression from empirical practices to scientifically grounded methodologies. Early civilizations employed soil for various purposes, such as flood control, burial sites, and building foundations. The transition from an art to a science began in the 18th century, marked by advancements in earth pressure theories and soil classification.
Notable contributions include Darcy’s Law in the 19th century, which describes fluid flow in porous media, and the development of soil mechanics principles by Karl von Terzaghi in 1925. Terzaghi’s work laid the foundation for modern geotechnical engineering, introducing concepts like effective stress and theories on bearing capacity and settlement prediction.
Key Developments

Charles Coulomb’s work in 1773 initiated the application of mechanics to soils. He proposed methods to determine earth pressures against military ramparts, emphasizing the role of soil cohesion.
Darcy’s Law and Stress Distribution (19th Century)
Henry Darcy’s formulation of Darcy’s Law, Joseph Boussinesq’s stress distribution theories, and William Rankine’s alternative to Coulomb’s earth pressure theory significantly contributed to the understanding of soil behavior.
Terzaghi’s Contributions (1925)
Karl von Terzaghi’s seminal work in 1925 marked the inception of modern geotechnical engineering. He introduced the principle of effective stress, bearing capacity theories, and settlement prediction for clay layers.
Critical State Soil Mechanics (1958)
Roscoe, Schofield, and Wroth established critical state soil mechanics, linking volume change behavior with shearing behavior. This forms the basis for contemporary constitutive models describing soil behavior.
Observational Method (Learn-as-You-Go)
Proposed by Terzaghi and discussed by Ralph B. Peck, the observational method allows construction modifications based on real-time measurements and assessments, contributing to overall project economy without compromising safety.
