“…The limit T values found in this study for drained and undrained conditions during cone penetration were compared to other researchers [3,8,14,18,20,21,28,30,46]. Based on these researchers' findings, the drain and undrain boundary ranges were determined between 0.01 to 1, and 6 to 75, respectively.…”

“…Several researchers have taken into consideration the drainage condition effect in their experimental [5,9,18,20,23,24,30,37] and numerical investigations [3,14,17,18,20,40,46] by studying the effect of the c h , v, and d on the cone tip resistance and excess pore pressure during the cone penetration into the soil. Schneider et al [37] found that the overconsolidation ratio and silt content significantly affected the q c and u. Kim et al [21] suggested the limiting values of T for drained and undrained conditions as 0.05 and 10, respectively.…”

“…They found the T for drained and undrained transition points between 0.01 and 20. Oliveira et al [30] used centrifuge tests performed at variable v values using a mini-CPT probe and presented an analytical approach. Their research found the transition value of T for drained and undrained conditions between 1 and 75, respectively.…”

The influence of drainage conditions on cone penetration test (CPT) resistance and the excess pore pressure during cone penetration in sand and silty sand are examined using field and physical model tests. Drainage can generally occur in saturated clean sand and silty sand under certain conditions. This work aims to understand and explain the effect of sand and silty sand drainage conditions on CPT resistance and pore pressure through the coefficient of consolidation (c h ) and penetration rate (v). The physical model test results indicate the significant effect of excess pore pressures and their dissipation rates, depending on the coefficient of consolidation (silt content) and the penetration rate on cone resistance. For the same relative density, normalized CPT resistance decreases as there is a reduction in c h (or an increase in silt content) or an increase in penetration rate. The difference in CPT resistance in silty sand is attributed to drainage conditions. Finally, the results revealed in this study and the field test data reported in the literature were combined to develop an equation for the effect of drainage conditions on excess pore water pressure and CPT resistance.

“…[7] introduced a so called Inverse Filtering, an iterative procedure, to estimate the unaffected 𝑞 𝑐 and sleeve friction (𝑓 𝑠 ) with sharp transitions. Several other researchers also investigated the CPT results in layered soils both experimentally (e.g., chamber test: [8], [9] and [10]; and centrifuge test: [11]) and numerically (e.g., cavity expansion: [12]; and axisymmetric penetration analysis: [13], [14] and [15]).…”
