Coefficient of consolidation (ch) and relative density (Dr) are major parameters to explain soil behavior of silty sands. In this study, it was aimed to compare the effects of ch and Dr of drained, partially drained and undrained soils on cone penetration resistance and excess pore water pressure. Several field tests; piezocone penetration test (CPTu), standard penetration test (SPT), pore pressure dissipation test (PPDT) and direct push permeability test (DPPT) were conducted on the Northern side of the Izmir Gulf at 20 different locations in 2013 by Ecemis et al. At each location between Cigli and Karsiyaka tests were performed 2.6 m apart from each other. The cone resistance qc, the frictional resistance fs, and pore water pressure behind cone u2 were obtained from CPTu tests. During the investigation, the effect of ch obtained from PPDT and DPPT which were conducted at the same depths for each borehole could be examined. SPT tests were used to estimate the Dr of the soil. The disturbed soil samples collected from the boreholes were classified as poorly graded clean sand (SP) to silty sand (SM) and clayey sand (SC). Results showed that qc decreased and u2 increased as the non-dimensional penetration rate (T= vd/ch) increased at the same Dr. From drained to undrained penetration, limit values for the T were determined, and it was seen that T and Dr influenced qc and u2 from medium dense to loose silty sands. Also, it was observed that u2 will be negative for denser silty sands.
