Theoretical Soil Mechanics

Foundational monograph that establishes the theoretical basis of modern soil mechanics. Terzaghi develops the concepts of effective stress, consolidation, permeability, seepage and shear strength, and links laboratory test results with field performance. For slopes, he shows how pore water pressures reduce effective stress and how drainage, stratigraphy and loading history control stability. The book underpins most later limit-equilibrium and numerical approaches to slope stability.
