Explanation of Terminology
Mohr-Coulomb Failure Criteria:
Tb = c'+oB' tan ~,
TB=c+aBtan~
Where
c', c = effective and total cohesive intercept
~', ~ =effective and total friction angle
Trc = Shear Strength on the failure surface at failure
6'q an= effective and total normal stress on the fatlure surface at failure
Stress Path Saace:
6~-t?_~ ~ t7t+t7~3
4= 2 P= Z
• Where:
q = shear stress
p', p = mean effeGive and total stress
6~' • 6' =Effective and Total Adel Stress
6~' ~ 6' = Effective and Total Cont'uung Stress
y=a+ptan(u
6t +Qi
P 2
Where:
a', a = intercept of the q-axis in effwtive stress of total stress space
w' W = angle of the failure line in effective stress of total stress space
p' = mean effective stress
p-Uo = mean total minus the initial pore pressure
with the relationship between ~ and ~ and a and c are as follows:
[an(w) = sin()
a = c * cos()
