Geotechnology: An Introductory Text for Students and Engineers focuses on the principles, methodologies, approaches, and applications of geotechnology. The publication first elaborates on engineering in earth materials and behavior of earth materials under static load. Discussions focus on rheological properties of earth materials, elastic materials, plane strain, stress, systematic description of geological factors, engineering classification of rocks and rock masses, classification of soils for engineering purposes, and soil and rock mechanics. The text then examines time-dependent behavior of earth materials, failure criteria for soils and rocks, engineering properties of soils, fluids in soils and rocks, and laboratory measurement of load, stress, and strain in earth materials. The manuscript examines the gathering and recording of data on geology, rock structure, and rock classification, application of models to geotechnology, response of earth materials to dynamic loads, and observation of mass deformations in geotechnology. The publication is a vital source of data for students, engineers, and researchers wanting to explore geotechnology.
