This chapter discusses the physical properties of soils, which are essential for understanding their behavior in geotechnical engineering. It first introduces fundamental parameters such as grain size distribution, density, and porosity, which directly influence soil permeability and strength.
Next, it explores the consistency of fine soils, particularly Atterberg limits (liquid limit, plastic limit, and shrinkage limit), which classify soils based on their plasticity and water content.
The chapter also covers weight-volume relationships, including water content, dry density, and saturation, which are crucial for compaction and stability analysis.
Finally, the concepts of soil structure and texture are discussed to explain the arrangement of particles and their influence on the mechanical behavior of soils.
This chapter provides a fundamental basis for studying the mechanical and hydraulic properties of soils in geotechnical engineering.
