Insights from CPTu and Seismic Cone Penetration Testing in the Kathmandu Valley, Nepal

Frontiers in Built Environment, 2021
Seismic hazard assessment often relies on static piezocone penetration tests (CPTu) to estimate the cyclic resistance ratio (CRR) and for the evaluation of in situ soil behavior.

CPTU-based probabilistic model and evaluation method for liquefaction of sandy and silty soils

Yantu gongcheng xuebao, 2023
The liquefaction of cohesionless soils is closely related to the pore water pressure. The in situ testing technology, piezocone penetration test (CPTU) which can directly measure the pore water pressure, has unique advantages in liquefaction evaluation ...

Machine learning-enhanced soil classification by integrating borehole and CPTU data with noise filtering

, 2021
Integrating borehole and piezocone penetration test (CPTU) data in site characterization helps to achieve a more comprehensive understanding of ground conditions. However, soil types at CPTU and nearby borehole locations may not always be consistent. The
