The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...

Geotechnical map of a coastal and industrialized urban area (Avilés, NW Spain)

open access: yesJournal of Maps, 2017
Geotechnical mapping of urban environments is usually constrained by the scarcity of outcrops during fieldwork. Such is the case of Avilés, a coastal Spanish city that has been heavily industrialized since the middle of the last century.

Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.
