Soil Engineering Characteristics

Question 1

Name five types of soil deposits

Answer 1

Glacial
Marine
Alluvial
Elian
Collusion

Question 2

What are the engineering characteristics of glacial till?

Answer 2

Heavily over consolidated
200-800kpa bearing capacity
Frictional and cohesive strength
Very low compressibility
Low permeability

Question 3

What are six most important engineering characteristics of soils?

Answer 3

Strength, shear and cohesion
Deformation, compressibility and consolidation
Permeability, hydraulic conductivity
Uniformity
Variability 
Aerial and vertical extent

Question 4

What are the engineering characteristics of alluvial deposits

Answer 4

Poorly graded depends on depositional environment
Normally consolidated
Non cohesive
Variable permeability

Question 5

What are the engineering characteristics of aeolian deposits?

Answer 5

Poorly graded
Non cohesive
Moderate permeability
Moderate compressibility

Question 6

What are the engineering properties of colluvium

Answer 6

Well graded
Loose and uncosolidated
Variable permeability
Can be low strength

Question 7

What is the difference between a residual soil and a transported soil?

Answer 7

A residual soil is the product of weathering and remains in place
If the products are transported than they are considered transported soils
