QUASI-STATIC DEEP PENETRATION IN CLAYS

Deformations caused by the steady-state penetration of a rigid rough wedge in caly are compared with theoretical predictions. It is found that the mechanism of sharp wedge penetration was consistent with the cutting process assumed by the theory. However, the larger the apex wedge angle the less accurate are the theoretical predictions. The mechanism of blunt wedge penetration is one of compression in which a rigid region fo clay moves with the wedge, so that the deformation patterns are difficult to interpret. Measured penetration resistance is in reasonable agreement with the theory. The suitability of plasticity theory to resolve penetration problems is assessed and its deficiencies identified. /ASCE/
