Instrumented Cone Penetrometer for Dense Layer Characterization

Abstract: Subsurface characterization is essential for a successful infrastructure design and construction. This paper demonstrates the use of an instrumented cone penetrometer (ICP) for a dense layer characterization at two sites. The ICP consists of a cone tip and rods equipped with an accelerometer and four strain gauges, which allow dynamic driving, in addition to quasi-static pushing of the cone. The force and velocity of the cone are measured using the ICP instrumentation and compared with the N value, dynamic con… Show more

“…Notably, the displacement in Equations ( 3)-( 5) can be calculated using the signal recorded at the cone tip, while ∆d in Equation ( 2) is obtained by directly measuring the penetration depth. Recently, a force-based dynamic resistance has also been suggested by several researchers [18,19,25]. By adopting the same interval of integration as that used in Equations ( 3)-( 5), the dynamic resistances based on the force integration (F method) can be expressed as follows:…”

“…Lee et al (2019) proposed a novel strength index termed dynamic cone resistance (DCR), which is based on the cone tip dynamic response; it helps establish correlations with various soil strength parameters. To characterize deeper and denser layers of intermediate geomaterials, Lee and Byun (2020) developed a large-sized IDCP and utilized it in field studies, comparing its results with blow count profiles from SPTs. More recently, Kim et al (2021) conducted comparative analyses of various dynamic resistance estimation methods based on cone tip responses obtained from an IDCP.…”
