Important Question And Answer: Civil - Soil Mechanics - Soil Classification And Compaction


1.Define Soil mechanics.

 

Soil mechanics is defined as the application of the laws and principles of mechanics and hydraulics to engineering problems dealing with soil as an engineering material

 



Important Question And Answer: Civil - Soil Mechanics - Soil Water And Water Flow



10)What is shrinkage limit?

 

The shrinkage limit (SL) is the water content where further loss of moisture will not result in any more volume reduction.

 

11)    Define Liquid limit.

 

The plastic limit (PL) is the water content where soil starts to exhibit plastic behavior. A thread of soil is at its plastic limit when it is rolled to a diameter of 3 mm and

 

crumbles. To improve consistency, a 3 mm diameter rod is often used to gauge the thickness of the thread when conducting the test.

 

12)    What is Plasticity Index?

 

The plasticity index (PI) is a measure of the plasticity of a soil. The plasticity index is the size of the range of water contents where the soil exhibits plastic properties. The PI is

 

the  difference  between  the  liquid  limit  an

 

PI tend to be clay, those with a lower PI tend to be silt, and those with a PI of 0 tend to have little or no silt or clay

 

13)    Define the term Liquidity Index.

 

The liquidity index (LI) is used for scaling the natural water content of a soil sample to the limits. It can be calculated as a ratio of difference between natural water content,

 

plastic limit, and plasticity index: LI=(W?PL)/(LL?PL)  where  W  is  th

14)    Define effective stress.

 

Effective stress (?') acting on a soil is and pore water pressure (u) according to Typically, for simple examples

 

 

15)    What is pore pressure?

 

Pore water pressure refers to the pressure of groundwater held within a soil or rock, in gaps between particles (pores)

 

16)    What is cohesion?

 

Cohesion is the component of shear strength of a rock or soil that is independent of interparticle friction.

 

17)    What is overburden pressure?

 

Overburden pressure, lithostatic pressure, and vertical stress are terms that denote the pressure or stress imposed on a layer of soil or rock by the weight of overlying material.

 

18)    Define Bulk Density?

 

It is defined as the mass of many particles of the material divided by the total volume they occupy

 

19)    What is seepage?

 

Seepage is the flow of a fluid through soil pores.

 

20)    What is the use of flownet?

The quantity of seepage under dams and sheet piling can be estimated using the

 

graphical construction known as a flownet The Mohr?Coulomb failure the most common empirical failure criterion used in soil mechanics. In terms of

effective stress the  Mohr?Coulomb  criterion  is  define

Tf=c’ + Ro ‘t tanO’

21)    What are the various soil classification systems in practice?

 

Various Soil Classification Systems:

 

1? Geologic Soil Classification System 2? Agronomic Soil Classification System

 

3?  Textural  Soil  Classification  System  (U

 

4?AmericanAssociationof State Highway Transportation Officials System (AASHTO)

 

5? Unified Soil Classification System (US 6? American Society for Testing and Mater
