Final Test- Chapter 1

What would be a good definition for geotechnics?

• It is the study of methods for quantifying the forces between bodies

• It involves defining the soil's strength and deformation properties.

• It is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them

• It is a material composed of five ingredients such as: minerals, soil organic matter, living organisms, gas, and water.

what are the three phases of a soil?

• Liquid pase, solid phase and gaseous phase.

• hot phase, solid phase and mineral phase.

• foundation phase, early phase and late phase

• fluid, pores and inertia

Which of these images belongs to a granular soil?

• 
• 
• 
• 

what are the 4 loading processes in which a failure analysis should be done?

• earthquakes, explosions,balance and shear

• waves, traffic, dynamic behavior

• macroscopical, molecular and atomic analysis

• earthquakes, explosions, waves and traffic

What are the main characteristics of Deformation range

• The options c and d are correct

• how particles of soil are grouped together into aggregates

• Evaluates the available resistance of the soil and the stresses

• Analyzing ground settlements by evaluating the behavior of the soil

Which of these images best represents stress vs strain?

• 
• 
• 
• 

According to “Effect of repeated loading” there are two types of problems; which are “dynamic and static”, this statement is:

• True

• False

This Definition:” Conventional triaxial test involves subjecting a cylindrical soil sample to radial stresses” refers to:

• Dynamic loading processes

• Failure analysis

• Triaxial test

• Deformation range

What are the three main types of triaxial tests?

• cyclic load testing, Monotonic static and detonation

• axial displacements, axial stresses and rubber membrane

• dynamic process, vibrations test, cyclic frequencies

• Consolidated– Drained, Consolidated – Undrained and Unconsolidated – Undrained

The specimen in a triaxial test is:

• a mechanical tool

• a soil sample

• a method of testing

• a rubber membrane
