Question:-
Option (A) Option (B) Option (C) Option (D) Correct Option:
C
Question Solution:
When all the stresses are assumed to be tensile, then strain in any particular direction is given as
εx = Here σx = - σ1; σy = - σ2; σz = - σ2
therefore, (εy)c = = => (εy)c = ...(i)
when σx = -σ1; σy = 0; σz = 0, then
y)a = => (εy)a = ...(ii)
But, (εy)c = => = => μσ1 + μσ2 - σ2 = => = σ2(1 - μ)
=> σ2 = Question:-
Option (A)
Consolidated Undrained Test (CU)
Option (B)
Unconsolidated Undrained Test (UU)
Option (C)
Consolidated Drained Test (CD)
Option (D)
All are equally suitable
Correct Option:
B
Question:-
Option (A)
15.6°
Option (B)
10.6°
Option (C)
8.6°
Option (D)
13.6°
Correct Option:
C
Question Solution:
Given,
φ' = 30°; &γsat = 21 kN/m3;
F = 2; &β = ?; &γ' = &γsat - &γw
We know that,
Factor of safety
F = => 2 = => tan&β = => &β = 8.6°
