The residual shear strength is defined by the post-peak strength behavior of strain-softening materials, as sketched in Fig. 1.
SOIL STRENGTH PROPERTIES AND THEIR MEASUREMENT
onlinepubs.trb.orgsure. The shear strength can be expressed consis-tently in terms of effective stress: s=c'+a'tan4)'=c'+(a—u)tan4)' (12.4) where c' and 4)' are the strength parameters for effective stress. For a partially saturated soil, the shear strength can be expressed as (Fredlundet al. 1978) s = c' + (a - u) tan4)' + (u - u0) tan4)" (12.5) where

The undrained strength parameters were estimated using the curves and transformation equations shown in Figure 5.2(b), with emphasis on values measured at cell pressures less than 7 psi. The total stress parameters for the natural soils, determined in this manner, are as follows:

people.eng.unimelb.edu.auThe results of a number of direct shear tests on samples of a soil have been plotted in Fig. 8.12. The line drawn through the points gave strength parameters of c = 20kN/m 2 and φ = 30˚ For the test in which the shear stress at failure and the normal stress were 37kN/m 2 and 30kN/m 2 respectively (point A in Fig. 8.12) determine
