GeosciencesCase histories have shown that the liquefaction behavior of soils can differ depending on the pre-seismic history of sites. Assessing the shear modulus in soils subjected to seismic events is critical for advancing the fundamental understanding of soil ...

Influence of clay mineralogy on undrained cyclic strength of sand with fines
Engineering Science and Technology, an International JournalSoils in natural or reclaimed areas frequently contain a mixture of sand, silt, and clay, rather than consisting solely of clean sand. The influence of a small proportion of fine plastic particles within a sandy matrix on liquefaction resistance still ...

Correction of Mechanical CPT Data for Liquefaction Resistance Evaluation
World Congress on Civil, Structural, and Environmental Engineering, 2016 For more than 30 years, there has been considerable interest in using CPT also to evaluate the liquefaction resistance of soils. Unfortunately, most of the simplified methods used for liquefaction resistance evaluation only require in situ measurements from electrical cone penetrometers even if they are frequently applied using measurements from ...

Correlation Between Liquefaction Resistance and Shear Wave Velocity
Soils and Foundations, 1990 ABSTRACT Undrained cyclic triaxial tests were conducted using various sands under different confining pressures, to establish a relation between liquefaction resistance and shear wave velocity or elastic shear modulus. The test results together with those of previous studies indicate that the correlation depends on such factors as soil type and ...

Earthquake induced liquefaction hazard analysis for Chittagong City using machine learning
Geomatics, Natural Hazards & RiskLiquefaction hazard analysis is crucial in earthquake-prone regions as it magnifies structural damage. In this study, standard penetration test (SPT) and shear wave velocity ([Formula: see text]) data of Chittagong City have been used to assess the ...

On the undrained cyclic resistance of a partially saturated sand [PDF]
E3S Web of ConferencesThe undrained cyclic resistance of sandy soils is a key factor in controlling earthquake-induced damage. It is well established that the degree of saturation significantly influences the undrained behaviour of sands, as a reduction in saturation ...
