Consolidated Undrained Triaxial Lab Data

Project: MONTGOMERY WATSON/LAB TEST/CO
Project Number: 003-21 ] 1-1
Explination of Terminology
Mohr-Coulomb Failure Criteria:
T.ry = c'+Qg'tatt ~'
Th=c+a~tan¢
Where:
c', c = effective and total cohesive intercept
~', ~ = effective and total friction angle
iR = Shear Strength on the failure swface at failure
6~a~ 6a= effective and total normal stress on the failure surface at failure
Stress Path Space:
2 2
Where:
q = shear stress
p', p = mean effective and total stress
6~' ~ 6' =Effective and Total Axial Stress
6~' • 6' = Effective and Total Confining Stress
y=n+p'tanyi
6i +6-:
P z
Where:
a'; a = intercept of the q-axis in effective stress of total sues, space
~' W = angle of the failure line in effective sues, of total sues, space
p' = mean effective stye„
p-Uo = mean total mmus the initial pore pressure
tadth the relationship benveen Vi and ~ and a and c are as follrnvs:
tan(w) = sm(~)
a = c * cos()
