    Abstract

    The present laboratory study investigates the effect of varying the apex angle on cone penetration resistance in clay. In order to reduce the cost associated with the field sampling of large blocks of sensitive clay, an artificially cemented material was conceived and tested. Steady cone penetration tests were carried out in 200-mm-diameter by 1000-mm-long cylinders of artificial clay. The 10-mm-diameter cones used were characterized by apex angles of 7.5, 15, 18, 22.5, 30, 45, 60, 90, and 180°. Penetration resistance factors Nc were obtained for each cone. The results show that the values of these factors are much larger than those predicted by existing theoretical approaches.
