Piezocone Identification of Organic Clays and Peats
A recent study of over 40 organic clay sites subjected to piezocone penetration tests (CPTu) found that the conventional soil behavioral type charts did not identify these materials properly (specifically zone 2), but instead were mostly categorized as either zone 3 (clays) or zone 4 (silts). An alternate CPTu methodology is presented for a more reliable approach to detecting organic clays and peats which mainly requires three parameters: net cone resistance, effective cone resistance, and excess porewater pressures. Once properly identified, a simple expression is used to assess the profile of effective preconsolidation stress in these organic geomaterials in terms of the net cone tip resistance in a power law format.
