摘要: |
Extensive experience gained with the dynamic cone penetrometer (DCP) in Israel has led to some modifications in both the testing apparatus and the testing procedure. One such modification is introduction of a theoretical corrective equation when the penetration is not performed vertically in order to isolate the skin friction that develops along the penetrating rod, which significantly affects DCP values. For this purpose, the torque moment is measured at various penetration depths by the same technique applied for the well-known Vane test. This corrective equation is then modified in light of the results obtained for validating in situ DCP tests. |
