Vertek CPT: How pore pressure data is used to correct and analyze CPT data? Sponsored

In continuation to the previous article provided by Vertek CPT University, pore pressure sensors are common to most modern CPT cones, enhancing the soil profiling procedure. But how pore pressure data are used to correct and analyze CPT data?

Pore pressure data are used to correct or “normalize” sleeve friction and cone resistance readings in the presence of in-situ moisture and overburden stress. This is especially important in soft, fine-grained soils where in-situ moisture takes longer to dissipate, and in tests at depths greater than 100 feet. Corrections based on pore pressure data also help standardize soil behavior type characterizations when CPT cones of different shapes and sizes are used.
