12 Questions
What is the portion of total stress that is carried by water in saturated soil without seepage?
Portion carried by water in the continuous void spaces
What does the effective stress represent in a soil mass?
The sum of vertical components of forces at points of contact in the soil mass
Which term is used to describe the hydrostatic pressure at a specific point in the soil?
Pore water pressure
What is the space occupied by water equal to in a soil mass according to the text?
Cross-sectional area occupied by solid-to-solid contacts
Which term is used to refer to the value of neglected pressure in practical problems?
Neutral stress
In a saturated soil with seepage, how does the effective stress at any point differ from the static case?
It increases or fluctuates with seepage flow
What is the purpose of analyzing the distribution of stress along a given cross section of the soil profile?
To determine the compressibility of soils
What is the effective stress concept related to in soil mechanics?
Distribution of stress in a soil mass
Why is it necessary to estimate the net increase of vertical stress in soil during foundation construction?
To calculate settlement that may occur
In a given soil volume, what occupies the void spaces between solid particles?
Both water and air
When analyzing problems like bearing capacity, what fraction of the normal stress in a soil mass is carried by water in the void spaces?
A significant fraction
