Effects of particle shape on the liquefaction resistance of sands

, 2019
The cyclic behavior and liquefaction resistance of sands is a subject area of long standing interest. Difficulties in estimating the liquefaction resistance of sands arise from the combined effects of various factors such as gradation, particle shape ...

Influence of clay mineralogy on undrained cyclic strength of sand with fines

Engineering Science and Technology, an International Journal
Soils 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 ...

Surface Consistent Seismic Hazard Assessment in the Shillong Plateau, Northeast India: A Probabilistic Approach Using Multiple Source Models and a Logic Tree Framework

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.

Energy-Based Assessment of Liquefaction Resistance of Rooted Soil

, 2022
Plant roots have been shown to improve the soil resistance to liquefaction upon cyclic loading. However, the effect of roots and their orientations on any changes in soil anisotropy and the mechanisms of dissipated energy involved at liquefaction state ...

Uneven Impacts of Seawall Heightening on Tsunami Risk Reduction under Rising Sea Levels: Probabilistic Scenarios from the Japan Trench

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Disasters exacerbated by climate change have prompted adaptation measures, including seawall heightening, which is an effective approach to protecting coastal areas. However, the combined effect of rising sea levels and tsunamis can create a compound coastal hazard, in which long‐term sea level rise amplifies the impact of tsunamis.

Earthquake induced liquefaction hazard analysis for Chittagong City using machine learning

Geomatics, Natural Hazards & Risk
Liquefaction 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 ...

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 ...

Membrane penetration reduction technique for undrained cyclic torsional shear tests on gravelly soils

Soils and Foundations
This study investigates the liquefaction behavior of gravelly soils using undrained torsional shear tests, with a focus on mitigating membrane penetration effects. A novel approach is proposed involving a 4-mm-thick sand coating (the membrane-penetration-
