The strength of a soil, or the ability to compact a soil into a suitable construction material will depend
on? correct answersSoil type
Soil density
The amount of water in the soil
Types of soils correct answersGravel (mm to cm's in size)
Sand (mm in size)
Silt (fine particles with little cohesion)
Clay (has cohesion, can stick together)
Organic soils (peat, topsoil)
Organic soils (O) correct answersHave a large componet of dead or decaying plants, and are not used in
construction
Silt and Clay correct answersClassified based on whether the soil is plastic or non-plastic (eg. can you roll
it into a ball)
Gravel and Sand correct answersare classified based on whether or not all the particle are roughly the
same size(uniform, like a beach) or if there is large variety in particle size (well-graded)
Soil layers correct answers1. (complex zone) 3 to 4m
2. (glacio-lacustrine clay) 2-12m
3. Glacial till, up to 9m in thickness
4. Carbonate bedrock, the upper surface of which is often fractured, weathers and irrgular
Soil has two componets of strength correct answersCohesion (clay only)
Friction (when individual soil grains move across on another)
,Soil fail by correct answersshear
Soil strength is used to determine correct answersThe bearing capacity of a foundation
The stability of natural or man-made earth slopes or retaining walls
Test for soil strength include; correct answersunconfined compression test
direct shear test
Triaxial compression
Soil strength depends upon correct answersDensity and moisture content
Unconfined compression test correct answersuseful for comparing strength of two soils or varion of
strength with dept.
Gradation refers to the range of measured soil particle sizes. Gradation results in classifying soil as?
correct answersGravel ( > 2 mm)
Sand (between 0.075 and 2 mm)
Silt (0.002 to 0.075 mm)
Clay (< 0.002 mm)
The particle size distribution of coarse-grained soils is typically determined by? correct
answersMechanical sieve analysis
The particle size distribution of fine-grained soil is determined using a ? correct answershydrometer
analysis
Two parameters help to identify soils that are well-graded? correct answersThe Coefficient of Uniformity
(Cu)
The Coefficient of Curvature (Cc)
, The hydrometer analysis is used to determine the gradation of correct answersslit and clay-sized
particles.
Only soil particles passing the No. 40 sieve(0.425) are used in the correct answershydrometer analysis
Hydrometer readings give us two things? correct answersThe specific gravity, or density, of the fluid tells
us the % of material is still in suspension.
The average downward velosity of the hydrometer can give us the diameter of the particle hat is just
coming out of solution.
The Swedish soil scientist, _____developed a method of quantitatively describing the effect of soil
moisture on the consistency of fine-grained soils. correct answersAtterberg,
Although Atterberg proposed five limits only the following three are in common useage today. correct
answersLiquid Limit
Plastic limit
Shrinkage limit
Only the Liquid Limit and Plastic Limit are normally used to? correct answersclassify soil plasticity
It is important to remember that all values related to the Atterberg limits are simply? correct
answersmoisture content values.
moisture content = correct answersmass of water in the soil ÷ mass of dry soil
The Liquid limit (LL) is correct answersThe moisture content above which the soil behaves as a liquid.
The plastic limit (PL) is correct answersdefined as the moisture content above which the soil behaves as a
plastic; where plasticity is defined as the ability of a soil to undergo deformation at a constant volume.
