Using Passing Trains as Seismic Sources for Refraction Microtremor Site Characterisation Surveys: Rugeley, Staffordshire, UK

open access: yesIraqi Geological Journal, 2023
Microtremor seismic surveys are routinely used to provide shear wave velocities that are converted to soil stiffness site profiles. In this paper, we look to assess the feasibility of using trains as seismic sources to characterize near-surface ...

Fuzzy set concept in structural geology: Example of ductile simple shear

open access: yesJournal of Earth System Science, 2021
Much of the time, geological data are not accurately known. Instead, geoscientists work with a range of possible data. These data can have a range since they can vary spatially and temporally. In this context, we demonstrate how a well-established structural geological model of velocity profile of ductile simple shear, expressed as an equation, can be ...

Mechanism of rockfall coupled with endogenic and exogenic geological processes: A case study in the upper Triassic limestone mines in the Qamdo area, eastern Tibet

open access: yesDizhi lixue xuebao, 2022
Rockfall in limestone mines is a common geohazard in the Changdu area of eastern Tibet and one of the leading geo-safety issues that mining enterprises and railway projects are faced with.

Primary characteristics of the extreme heavy rainfall event over Henan in July 2021

open access: yesAtmospheric Science Letters, Volume 24, Issue 1, January 2023., 2023
China is located in the East Asian monsoon region, which experiences relatively frequent heavy rainfall events in summer. Generally, the heavy rainfall frequency and accumulated amount in South China are higher than those of North China, whereas, the intensity of heavy rainfall in North China is similar to or even higher than that of South China.

Connecting shear localization with the long-range correlated polarized stress fields in granular materials

open access: yesNature Communications, 2020
Understanding the behavior of jammed granular matter is important for a range of phenomena, from materials science to geology. Wang et al. uncover relations between stress correlations and emergence of localized shear bands due to external shear stress ...

Assessing the liquefaction potential of seabed soils based on ocean ambient noise in the Yellow River Delta

open access: yesFrontiers in Marine Science, 2023
Seabed soils can undergo liquefaction under cyclic loading, resulting in a rapid decrease in strength and stiffness, which may lead to the destruction of offshore structures.
