Overconsolidated (OC) soils may develop a low or negative pore pressure during PCPT. Thus, it is challenging to an “on-the-fly” estimation of hydraulic conductivity from PCPT results. This study presents method estimate the OC results based on previously developed for normally consolidated (NC) soils. To apply existing method, in adjusted by using correction factor. An equation factor derived c...

Piezocone penetration test device imported from the Netherlands was used to conduct pore pressure dissipation tests at 4 measuring points in 2 holes water area of Sutong GIL utility tunnel project. After dissipation, stable analyse groundwater and further obtain height head. This method provides a successful solution for in-situ stratification testing parameters engineering, reliable hydrologic...

This study presented a framework for uncertainty analysis of the ultimate axial bearing capacity piles evaluated by UniCone method in layered soils. The Eslami and Fellenius (1997) is direct piezocone penetration test (CPTU) evaluating reliability design. spatial variability CPTU data modeled as random field each soil unit strata. empirical correlation coefficients are assumed to follow lognorm...
