Explore geotechnical engineering basics with Nikhil Agrawal: part 1–5 cover soil identification and classification, part 6–9 cover soil properties, plus notes on slides in resources.
Study soil as a three-phase solid-liquid-gaseous system. Examine volumetric relations such as void ratio e and porosity n, and volume-mass properties to guide foundations, slopes, tunnels, and pavements.
Examine the fundamental properties of soil, including specific gravity and water content, and see how the soil-water relationship and temperature tested at 27 degrees Celsius affect soil density.
Identify and apply basic relationships in soil mechanics, including porosity, degree of saturation, and water content, for numerical analysis and engineering calculations.
Learn how index properties of soil and particle size analysis reveal the distribution of soil particle sizes. Explore sedimentation and electron microscope observations to interpret these properties for geotechnical decisions.
Explore how water content controls soil consistency, detailing the liquid limit and plastic limit and how these limits define soil's plastic and liquid states.
Explore soil classification systems—AASHTO, USCS, and Indian IS—and distinguish coarse and fine grained soils by particle size, plasticity, and Atterberg limits.
Analyze soil stresses under homogeneous, below water table, and partially saturated conditions using vertical stress, pore water pressure, and effective stress. Compute total stresses with unit weights gamma and gamma_w.
Learn the permeability of soil through Darcy's law, determine the coefficient of permeability via constant-head and falling-head tests, and analyze stratified deposits.
This lecture explains soil compaction by dynamic loading to reduce volume and expel voids, achieving maximum density at the optimum moisture content, and covers standard and modified proctor tests.
Analyze shear strength of soils through Mohr circle, principal and effective stresses, distinguishing frictional and cohesive soils, with lab and field tests like unconfined, triaxial, and wind shear.
Explore geosynthetics in civil engineering, polymeric materials used with soil, earth, or rock to enhance geotechnical properties through separation, reinforcement, filtration, drainage, and containment.
Learn how to determine the fineness modulus of soils through sieve analysis, record mass retained on standard sieves, and compute the index from cumulative mass retained and cumulative percent retained.
Reveals how a landslide occurred due to a bentonite layer under heavy rain and rising groundwater, exposing inadequate testing, misapplied stability assumptions, and a negligent permitting process.
The Complete Course on Geotechnical Engineering is ideally suited for the learners those who are beginning to study soil based on engineering perspective. The course covers the basic fundamental of soil mechanics and advances as per the curriculum of undergraduate students. It covers most of the topics included in the curriculum of most of the universities offering soil mechanics subject in Civil Engineering discipline.
