Question

Calculate the total pore water and effective vertical stress distribution along the given depth according to the information given in the figure and draw their graphs with a ruler.

Note: Show 3 digits after the comma.

q=21,358 kN/m?
A
H1= 1,871 m
В
Yn= 18,557 kN/m³
H2=1 m
Yn= 19,557 kN/m³
H3= 5,871 m
Yn= 20,557 kN/m³
D

Expert Solution

Step 1 SOLUTION

Pore water pressure :- It is the pressure generated around the soil particles due to the presence of water table. Its magnitude is same in all directions

Effective stress :-Compressibility and the strength of the soil depend on the stresses . These stresses are called effective stresses.

The total vertical stress acting at a point below the ground surface due to its all weight is known as effective stress
