Geophysical Engineering

Course Objective

The aim of this course is to introduce the students to the fundamental principles of soil mechanics and to ensure that students understand how these properties are used to
solve some geotechnical problems like classification, compaction, seepage, compression, consolidation, shear strength, lateral earth pressures and slope stability.

Learning Outcomes of the Course Unit

1   To be able to describe index and engineering properties of soils.
2   To be able to realize the effects of water on soil behaviour.
3   To be able to evaluate behaviour of soils under loading.
4   To be able to interpret results of soil mechanics laboratory tests.
5   To be able to solve engineering problems of soil mechanics.
6   To be able to interpret and report solutions of engineering problems.

Course Contents

Week Subject Description
1 BASIC CHARACTERISTICS OF SOILS: Weight-volume relationships.
2 Structural properties, clay minerals, index properties (grain size distribution, relative density, consistency).
3 Soil classification. Compaction of soils (laboratory compaction, field compaction, compaction control). Announcement of the first homework
4 SEEPAGE: Hydraulic gradient, Darcy, seepage velocity, seepage equation, flow net, hydraulic conductivity, capillarity and its effects on soil behaviour.
5 EFFECTIVE STRESS: Geostatic soil pressures (total, effective and pore water pressures). Influence of seepage on effective stress. Time dependence of effective stress change.
6 ONE DIMENSIONAL COMPRESSION AND CONSOLIDATION: One dimensional compression equation, oedometer test, preconsolidation pressure, compression of normally and over consolidated soils. Announcement of the second homework
7 Consolidation equation and its solution, consolidation ratio, U-T relationships, time dependent loading. Determination of coefficient of consolidation.
8 Midterm examination. SHEAR STRENGTH: Coulomb's shear strength envelope, Mohr-Coulomb failure criterion.
9 Shear strength tests: Triaxial compression test, direct shear test. Shear strength properties of soils (dry sand, saturated clay). Other strength tests (vane shear test, unconfined compression test).
10 LATERAL EARTH PRESSURES AND EARTH RETAINING STRUCTURES: Geostatic, limit (active and passive) lateral earth pressures.
11 Design principles of earth retaining wall and sheet pile wall. Announcement of the third homework
12 SLOPE STABILITY: Circular failure and method of slices. Infinite slope analysis, wedge analysis with active and passive pressures. Announcement of fourth homework
13 BEARING CAPACITY: Ultimate and allowable bearing capacity definitions, general shear failure approach.
14 STRESS INCREASE AND SETTLEMENT COMPUTATION: Point load, uniform loading, pressure bulb, consolidation settlement and elastic settlement.

Planned Learning Activities and Teaching Methods

Course topics will be presented and applications will be performed in class for the enhancement of the subjects. Students will prepare reports on the engineering analyses
done individually about soil classification and compaction, compression and consolidation, earth retaining structure and slope stability.
