Statistical Assessment of Simplified CPTU‐Based Hydraulic Conductivity Curves
Geofluids, Volume 2021, Issue 1, 2021., 2021 Classical theoretical approaches to evaluate CPTU‐based hydraulic conductivity gave the expression of a bilinear relation defined by KD - BqQt, for undrained and drained soils. In fact, a dividing line may be selected with a certain degree of subjectivity, and several undrained/drained points occur in opposite sites, which may make us doubt the ...

The Baltic Journal of Road and Bridge Engineering, 2023 The bearing capacity of screw cast in situ displacement piles is mostly unexplored. There is also insufficient research on piles in silty soils. Therefore, five cone penetration tests (CPT) and one piezocone penetration test (CPTu) using direct methods ...

Soil stratigraphy from seismic piezocone data and multivariate clustering in alluvial soil deposits: Experience in the Lower Tagus Valley region [PDF]
, 2022 The identification of soil stratigraphy at a given site is crucial for geotechnical analysis and design. This study addresses the delineation of soil stratigraphy from seismic piezocone penetration test (SCPTu) measurements.

Yantu gongcheng xuebao, 2022 The cone penetration test (CPT) is a commonly used technique to identify the liquefaction of sandy soil in the world but it cannot reflect the influences of pore water pressure (pore pressure) on the liquefaction behavior. The piezocone penetration test (

Evaluation method for sand liquefaction of Hong Kong-Zhuhai-Macao Bridge based on CPTU tests
Yantu gongcheng xuebao, 2017 The earthquake liquefaction is one of the direct causes for unstable ground and damage of upper structure. Therefore, the liquefaction assessment is an important part of anti-seismic investigation in engineering.

Classification of soft clay in Jiangsu Province based on piezocone penetration tests
Yantu gongcheng xuebao, 2021 The classification results of soft soils in Jiangsu Province are derived through the CPTU data. The soil classification methods based on the CPTU data are reiviewed, then the SBT (soil behavior type) method and the Ic (soil index) method are chosen to ...
