CONE PENETRATION IN VERY WEAKLY CEMENTED SAND. DISCUSSIONS AND CLOSURE

Two discussions of a paper with the aforementioned title by Puppala, Acar, and Tumay, published in this journal (Volume 121, Number 8, August 1995), are presented. Discusser Day focuses initially on drained residual cohesion, stating that it would be more accurate to exclude this value when computing sleeve friction. Day also assesses the value of cone penetration in very weakly cemented sands based on geological features, such as oversize particles, mineral concretions, and faults. Discussers Schnaid and Consoli provide tip resistance data from soundings made at a site in Brazil, which support the authors' finding that friction ratio cannot be used as the identifier of very weak levels of cementation. The discussers commend the authors for using calibration chamber tests to demonstrate the influence of cementation on cone penetration and further suggest complementary laboratory tests for an independent assessment of friction angle, enabling estimation of the appropriate cohesion intercept for design. Discussions are followed by closure from the authors.
