1.
In
a normally consolidated clay specimen, the following data are given from the
laboratory consolidation test.
e1 =1.10 𝞼=65.0
kN/m2
e2 =0.85 𝞼=240.0
kN/m2
a. Find the
compression index Cc.
b. What will be the
void ratio when the next pressure increment raises the pressure to 460.0 kN/m2?
Solution:
2.
A
cone penetration test was conducted, using an electric-friction cone, in a clay
deposit. The cone penetration resistance, at 6 m depth, was 800 kN/m2.
Sensitivity of the clay St
< 4, and its PI <
30. Ground water table was located at 2 m depth. The unit weight γ of
the clay above and below water table was 18 and 20 kN/m3, respectively. Find
the over consolidation ratio OCR, and the undrained cohesion cu.
