Geotechnical Civil Engineering Course

Lesson 1 • Soil Origin and Composition

Covers geological processes forming soils and their mineral constituents. Establishes the physical basis for understanding soil behaviour throughout the course.

Lesson 2 • Soil Compaction Principles

Examines the relationship between moisture content and dry density during compaction. Connects laboratory compaction results to field quality control standards.

Lesson 3 • Phase Relationships and Index Properties

Quantifies the solid, liquid, and gas phases within a soil mass. Provides the mathematical framework for all subsequent soil property calculations.

Lesson 1 • Soil Sampling Techniques

Covers disturbed and undisturbed sampling methods and sample quality criteria. Ensures students can obtain representative specimens for laboratory testing.

Lesson 2 • Drilling and Boring Methods

Examines rotary, auger, and percussion drilling techniques for soil and rock. Equips students to select the correct method based on ground conditions.

Lesson 3 • In-Situ Testing Methods

Introduces field tests that measure soil properties without sample extraction. Provides direct data for design parameters in conditions where sampling is difficult.

Lesson 4 • Borehole Logging and Reporting

Teaches systematic recording of subsurface stratigraphy and test data. Produces the geotechnical report that guides all subsequent design decisions.

Lesson 1 • Seepage Analysis and Flow Nets

Applies Laplace's equation to construct flow nets for two-dimensional seepage. Enables calculation of seepage quantity and pressure distribution beneath structures.

Lesson 2 • Soil Water Fundamentals

Covers capillarity, pore water pressure, and total stress concepts in saturated soils. Establishes the effective stress principle central to all geotechnical analysis.

Lesson 3 • Seepage-Related Failures

Identifies piping, heave, and quicksand conditions caused by uncontrolled seepage. Prepares students to evaluate and mitigate seepage hazards in design.

Lesson 1 • Settlement Prediction

Calculates immediate, primary, and secondary settlement components for loaded soils. Connects laboratory consolidation parameters to field settlement estimates.

Lesson 2 • Consolidation Theory

Develops Terzaghi's one-dimensional consolidation model and its governing equation. Explains how excess pore pressure dissipates over time under sustained loading.

Lesson 3 • Consolidation Rate and Drainage

Predicts the time required to achieve target consolidation using degree-of-consolidation curves. Evaluates drainage path length and vertical drain acceleration strategies.

Lesson 1 • Drained and Undrained Behaviour

Contrasts drained and undrained loading responses in clays and sands. Guides selection of short-term versus long-term strength parameters for design.

Lesson 2 • Mohr-Coulomb Failure Criterion

Introduces the friction angle and cohesion intercept as fundamental strength parameters. Provides the failure envelope used in all subsequent stability calculations.

Lesson 3 • Laboratory Shear Strength Tests

Covers direct shear, triaxial, and unconfined compression test procedures and data interpretation. Equips students to select the correct test for a given drainage condition.

Lesson 1 • Pile Capacity Analysis

Calculates single pile capacity using static analysis and dynamic testing methods. Validates design capacity through load testing and wave equation analysis.

Lesson 2 • Shallow Foundation Settlement

Estimates total and differential settlement for footings on sand and clay. Links settlement limits to structural tolerance criteria for design acceptance.

Lesson 3 • Bearing Capacity of Shallow Foundations

Applies Terzaghi and Meyerhof bearing capacity equations to spread and mat footings. Incorporates shape, depth, and inclination factors for realistic design conditions.

Lesson 4 • Pile Foundation Types and Behaviour

Classifies driven, bored, and auger-cast piles by installation method and load transfer mechanism. Establishes the basis for pile capacity and group analysis.

Lesson 1 • Groundwater Effects on Stability

Quantifies the destabilising influence of pore pressure on slope factor of safety. Evaluates drainage measures as a primary stabilisation strategy.

Lesson 2 • Limit Equilibrium Methods

Applies the method of slices, Bishop, and Janbu procedures to compute factors of safety. Compares method assumptions and accuracy for different slope geometries.

Lesson 3 • Embankment and Cut Slope Design

Applies stability analysis to the design of engineered embankments and highway cuts. Addresses staged construction and long-term stability requirements.

Lesson 4 • Slope Stabilisation Methods

Reviews geometric, drainage, reinforcement, and structural stabilisation techniques. Enables selection and preliminary design of appropriate remediation measures.

Lesson 1 • Gravity and Cantilever Retaining Walls

Checks sliding, overturning, and bearing capacity for mass and cantilever wall types. Connects wall geometry to soil pressure resultants for iterative design.

Lesson 2 • Sheet Pile Wall Design

Analyses cantilever and anchored sheet pile walls using free and fixed earth support methods. Determines embedment depth and maximum bending moment for section selection.

Lesson 3 • Mechanically Stabilised Earth Walls

Designs reinforced fill walls using metallic and geosynthetic reinforcement layers. Evaluates internal and external stability for both static and seismic conditions.

Lesson 4 • Lateral Earth Pressure Theory

Derives active, passive, and at-rest pressure distributions using Rankine and Coulomb theories. Provides the load basis for all retaining structure design calculations.
