In geotechnical engineering, in-situ tests, like standard penetration test (SPT) and cone (CPT), are essential to evaluate the underground conditions. SPT is a frequently used approach, while CPT considered one of best exploration apparatuses. However, there demand for correlation SPT-CPT that can be in design. This research aimed find relationships between test’s blow count (N) tip resistance ...

Abstract The system of seabed Cone Penetration Test (CPT) is a kind equipment for offshore investigations. Seabed CPT used to assess multiple physical properties marine sediments. Constant-rate penetration mechanism the core part CPT, which adopts dual-cylinder drive penetrate probe rod into seafloor sediments at constant speed (2cm/s). At present, domestic and its almost all rely on imports. I...

Abstract Each pile in an offshore wind farm may be designed solely on the results of a single cone penetration test (CPT) positioned at its center or based sample statistics calculated from multiple investigated locations same geotechnical unit. This study investigates quantitatively effects spatial variability soil efficacy two approaches to achieve reliable design. Random field theory is used...

Commercial cone penetration testing (CPT) equipment was adapted to allow penetrative testing in hard polar firn to depths of 10m. The apparatus is hydraulically driven, rate-controllable and able to penetrate firn with a resistance of 10MPa. It can be mounted on many types of typical polar vehicles, requiring connection to only hydraulics and 12V electricity. Data recorded include both cone tip...

Many semi-empiric correlations have been developed to estimate geotechnical parameters based on Cone Penetration Test (CPT) data for various types of soils. This paper aims classify soil CPT with several and compare the results some these correlations. In this study, field laboratory test were carried out from two closely spaced locations in estuary area Muaro Baru, Padang city. The was used de...

The assessment of pile drivability is the premise successful installation, and completely weathered (CW) rock may bring risk refusal. This paper presents a case driving refusal that occurred in CW gneiss layer. physical mechanical properties are analyzed based on results laboratory test, cone penetration test (CPT), standard (SPT). By comparing with those from intact gneiss, layer this study wa...

Frameworks for estimating soil properties from CPT penetration resistances must account for the effects of overburden stress on both the penetration resistance and the soil property of interest, including how such effects vary with soil type. For example, common procedures for estimating the liquefaction resistance of sands include functional terms that account for the effect of overburden stre...
