Correlations between mapping units of costal sedimentary basin and interpretation of piezocone test results are presented and discussed based on examples from Caravelas strandplain, (State of Bahia), Paranaguá (State of Paraná) and Guarujá bays (State of São Paulo), Brazil. Recognizing that the sedimentary environment was mainly controlled by sea level fluctuations led to the interpretation of ...

ABSTRACT: Although the piezocone penetration test (PCPT) has several advantages over traditional methods of sampling and laboratory analysis in determining representative properties of a soil deposit, the existing methods used to infer soil properties from PCPT data are not always reliable due to the complexity of cone penetration. In this study, it is proposed that the process of “data fusion”...

Silt sediments are frequently encountered in the coastal areas of the North Sea. Evaluation of the silt behaviour must ideally rely on in-situ tests, in particular the piezocone test. However, interpretation of piezocone data in silt sediments is problematic and derived parameters can seem to differ significantly from those obtained by investigating intact samples in the triaxial apparatus. Use...

seismic piezocone device (scptu) together with resonant column and cyclic triaxial test apparatus are employed to measure small strain shear modulus (g0) of carbonate sandy and clayey soils of southern coasts of iran. a large area of southern regions of iran is formed from clay, silt and sand. in this study, maximum shear modulus that is derived from both field (by seismic piezocone) and labora...

series of undrained monotonic triaxial tests and cone penetration tests were conducted on loose silty sand samples to study correlation between undrained shear strength of silty sands (sus) and piezocone test results. cpt tests were conducted at 27 silty sand samples in calibration chamber. the results indicate that, in low percent of silt (0-30%), as the silt content increases, the undrained s...

Saturated fine-grained soils can undergo large settlements over a long period of time. Therefore, the estimation of both the total settlement and the rate of change of cohesive soils under field loading is essential for geotechnical engineering design and analysis. The total settlement can be determined from deformation moduli such as the tangent constrained modulus, M, while the time rate of s...
