1. Introduction to Geotechnical Engineering

Question 1

It is defined as the uncemented aggregate of mineral grains and decayed organic matter (solid particles) with liquid and gas in the empty spaces between the solid particles.

Answer 1

Soil

Question 2

It is used as a construction material in various civil engineering projects, and it supports structural foundations

Answer 2

Soil

Question 3

It is the branch of science that deals with the study of the physical properties of soil and the behavior of soil masses subjected to various types of forces.

Answer 3

Soil Mechanics

Question 4

It is the subdiscipline of civil engineering that includesthe application of the principles of soil mechanics and rock mechanics to thedesign of foundations, retaining structures, and earth structures.

Answer 4

Geotechnical Engineering

Question 5

Founded soil mechanics. Father of
Soil Mechanics

Answer 5

Karl Terzaghi

Question 6

His contribution of retaining wall

Answer 6

Charles Augustin de Coulomb

Question 7

renowned for his ingenious designs of soil testing apparatus and fundamental research on seepage and soil liquefaction.

Answer 7

Arthur Casagrande

Question 8

What is soil liquefaction

Answer 8

is when a soil is not behaving as soil but water. It is seen on places that is prone to earthquake

Question 9

What is Seepage

Answer 9

It is where in the dams the waters travel under the dams and go through the other side

Question 10

His study provided a notable theory on earth pressure and equilibrium of earth masses

Answer 10

William John Macquorn Rankine

Question 11

The godfather of soil mechanics, he was directly responsible for a succession of celebrated tunneling and earth dam projects that pushed the boundaries of
what was believed to be possible.”

Answer 11

Ralph B. Peck

Question 12

They are constructed where soil layer at shallow depth (upto 1.5m) is able to support the structural loads.

Answer 12

Shallow foundations

Question 13

It is a type of foundation which is placed at a greater depth below the ground surface and transfers structure loads to the earth at depth.

Answer 13

Deep foundation

Question 14

Soil/Ground preparation prior to construction.

Answer 14

EARTHWORKS

Question 15

These are sections of sheet materials with interlocking edges that are driven into the ground to provide earth retention and excavation support.

Answer 15

Sheet piles

needs to be over the required depth

Question 16

What does Sheet piles material made off

Answer 16

made of steel, but can also be formed of timber or reinforced concrete

Question 17

These are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides.

Answer 17

Retaining walls

Question 18

What is the difference between Drilling and Driven

Answer 18

Drilling is they dug a hole using a drill while Driven is when they are hammering a they use a large machine to hammer to pile in

Question 19

The watertight enclosure from which water is pumped to expose the bed of a body of water in order to permit the construction of a pier or other hydraulic work.

Answer 19

COFFERDAM

Question 20

What is Cofferdam made of

Answer 20

sheet piles

Question 21

It is an economical technique used to stabilize existing slopes and to construct retaining walls from the top down.

Answer 21

Soil nailing

Nails the soil in slopes, the nails needs to be over the failing line

Question 22

A dam is a structure built across a river or stream to hold back water.

Answer 22

EARTH DAMS AND CONCRETE
DAMS

Question 23

It is the procedure typically defined as using mechanical means to improve/reinforce poor ground conditions.

Answer 23

GROUND IMPROVEMENT
TECHNIQUES

Question 24

It is when a geotechnical engineer visits your site to acquire and test soil samples. Tests will reveal the characteristics, nature, and reactivity of soil.

Answer 24

SOIL TESTING
