Overview

*"If a builder builds a house for a man and does not make its construction firm, and the house which he has built collapses and causes the death of the owner of the house, that builder shall be put to death."*

**The Code of Hammurabi, Babylon, Circa 2000 B.C.**

"*2600 People die every year due to Building collapse*."

**Disaster Management of India**

*Engineering is, foremost, about solving the real problems not only questions in your exams.*

**Soil -** (for Civil Engineers) an uncemented aggregate of mineral grains and decayed organic matter (solid particles) with liquid and gas in the empty spaces between the solid particles.

**Soil Mechanics -** is the branch of science that deals with the study of the physical properties of soil and the behaviour of soil masses subjected to various types of forces.

**Soils Engineering** - is the application of the principles of soil mechanics to practical problems.

**Geotechnical Engineering** is the subdiscipline of civil engineering that involves natural materials found close to the surface of the earth. It includes the application

of the principles of soil mechanics and rock mechanics to the design of foundations, retaining structures, and earth structures.

**KEY FEATURES**

- Topics are taught thoroughly and systematically to clarify the basic concepts and fundamental principles without weakening technical hardship.
- Many
are solved to demonstrate or to provide further insights into the basic concepts and applications of fundamental principles.*example problems* - The solution of each example is preceded by a
, which is intended to teach students to think about possible solutions to a problem before they begin to solve it. Each solution provides a*strategy*to guide the student in problem-solving which really help students for university examinations and for the conventional exam like ESE (Engineering Services Examinations).*step-by-step procedure*

**THE GOAL OF THIS COURSE,...**

- To understand the physical and mechanical properties of soils.
- To determine parameters from soil testing to characterize soil properties, soil strength, and soil deformations.
- To apply the principles of soil mechanics to analyze and design simple geotechnical systems.

**LEARNING OUTCOMES**

When you complete this video course you should be able to:

- Describe soils and determine their physical characteristics such as grain size, water content, and void ratio.
- Classify soils.
- Determine compaction of soils.
- Understand the importance of soil investigations and be able to plan a soil investigation.
- Understand the concept of effective stress.
- Determine total and effective stresses and porewater pressures.
- Determine soil permeability.
- Understand the effects of seepage on the stability of structures.
- Determine how surface stresses are distributed within a soil mass.
- Specify, conduct, and interpret soil tests to characterize soils.
- Understand the stress-strain behaviour of soils.
- Understand popular failure criteria for soils and their limitations.
- Determine soil strength and deformation parameters from soil tests, for example, Young’s modulus,
- friction angle, and undrained shear strength.
- Discriminate between “drained” and “undrained” conditions.
