“…Recently, analytical studies by Whittle and Aubeny (1992) and Aubeny et al (2000) showed that disturbance induced even during ideal self-boring (i.e., where the volume of the soil extracted exactly balances the volume of the soil displaced by the device) causes a reduction in lift-off pressure and excessive derived peak shear strengths with postpeak strain softening that are incompatible with the behaviour of the intact clay. These investigators also found that the predicted effect of increasing the ratio of the diameter of the cutting shoe relative to that of the pressuremeter membrane was in qualitative agreement with field studies indicating that increasing this ratio decreases the lift-off pressure and increases the derived shear strength Eden 1980, 1985;Benoît and Clough 1986).…”

“…This strain induces significant shear stresses before the start of the test. For the case of the self-boring pressuremeter (SBPM), the situation is improved, but either overpushing with an initial outward radial strain ε oi > 0 (Jefferies and Shuttle 1995) or overcutting with an initial inward radial strain ε oi < 0 Benoît and Clough 1986) may occur due to the installation of the pressuremeter. This will take place despite technical improvements such as the use of jetting (Benoît 1995) to increase the efficiency of the installation procedure.…”

“…Twenty tests were carried out at Pease AFB using the cutting technique, and results from previous investigations at Hamilton AFB using cutting (Denby 1978;Benoit 1983) were used in this study. Pushin-type pressuremeter tests were also conducted at both sites for comparisons.…”
