Description:Alternate CPT stress-normalization procedures have been proposed for the cone readings e. Therefore, it is more rigorous in the post-processing of CPT data to consider stress normalization schemes for all three of the piezocone read- ings. Page 27 Share Suggested Citation: Correspondingly, mea- sured porewater pressures depend on the position of the fil- ter element and groundwater level. As a general rule of thumb, the magnitudes of CPT mea- surements fall into the following order: Values in between these limits are indicative either of mixed sand-clay soils or silty materials, or else highly interbedded lenses and layers of clays and sands. In a recent and novel approach to indirect soil classifica- tion by CPT, a probabilistic method of assessing percentages of clay, silt, and sand has been developed by Zhang and Tumay
