System dynamic reliability evaluation of multiple failure modes of earth dams subjected to strong earthquake excitation

open access: yesSoils and Foundations, 2023
An earth dam in service is a complex system that has different dynamic failure modes under different ground motion excitations with a certain correlation between the different failure modes.

Earth-Rock Dams’ Breach Modelling

open access: yes, 2021
Simulation of dam breach process has significant influence on the evaluation of consequence of dam breach flood. In this study, research progresses on the numerical modeling of earth-rock dams’ breach process are summarized, especially the latest research results of the author’s research team in recent years. However, there still has a considerable gap

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Review on overtopping failure and flood evolution of earth-rock dams

open access: yesShui kexue jinzhan, 2020
Flood events caused by the overtopping failure of earth-rock dams often lead to catastrophic disasters. Therefore, examining the cause of the dam failure and studying the subsequent flood evolution processes are extremely important for disaster ...

Stress-strain state of earth dam under harmonic effect [PDF]

open access: yesE3S Web of Conferences, 2019
Stress-strain state of earth dams under the effect of harmonic (seismic) load from the base of the dam is numerically studied in the paper. Rock fill dam has good culvert properties and its water saturation is considered to have no effect on mechanical ...
