ENGR061 introduces the fundamental concepts of soil mechanics essential for studying and designing geotechnical structures. The course focuses on understanding the origin of soils from rocks, their behavior as engineering materials, and various soil classification systems. It also examines the impact of water in soil and how its movement affects soil properties, the distribution of stresses, and the analysis of soil response to loading. Additionally, the course explores soil strength, stress-strain relationships, and other relevant theories in engineering soil behavior.
