Q76
Shear strength of a soil is a unique function of
A.
effective stress only
B.
total stress only
C.
both effective stress and total stress
AnswerD.
none of the above
Answer: Option C
Solution
Answer: Option C
Solution:
In soil mechanics, the shear strength of a soil is a unique function of both effective stress and total stress.The shear strength of soil depends on both the effective stress and the total stress acting on the soil mass.
Effective stress refers to the stress carried by the soil grains themselves, while total stress includes the stress carried by both the soil grains and the pore water.
Therefore, the correct option is both effective stress and total stress.
