2308 Demonstration of the Applicability of the New CPTu/SCPTu Correlations with Soil Parameter Evaluation
The most accurate determination of seismic site class is achieved with in situ measurement of shear wave velocities. A seismic cone penetration test with pore water pressure measurement (SCPTu) can perform all of the functions of the CPTu, but has added capability to measure shear wave velocity at discrete depths. Shear wave velocities are not only useful for accurate determination of seismic site class, they can also be used to estimate other soil properties such as the small strain shear modulus (Gvo). The objectives of this research project are: (1) To demonstrate the applicability of various CPT, CPTu, SCPTu correlations to a broad range of Oklahoma soils. (2) To develop Oklahoma specific correlations based on laboratory and CPT, CPTu and SCPTu data collected. (3) To develop recommendations for addressing the impact of partial saturation on CPT, CPTu and SCPTu results and estimated soil properties. (4) To produce a comprehensive set of guidelines in a manual of practice for application of CPT, CPTu and SCPTu for geotechnical engineers in Oklahoma.
