Study on fracture parameter calibration and failure characteristics of rock with hole and crack

Deep Underground Science and Engineering, EarlyView.
The SIF and plastic zone equations for a single hole and crack have been derived. The model's failure state leads to the identification of four types of cracks. The plastic zone increases with increased brittleness and decreased crack length. Abstract Cracks within the surrounding rock of roadways significantly affect their stability and failure ...

Hazard assessment of seismic-collapsed loess landslides on the Loess Plateau as exemplified by the M6.2 earthquake in Jishishan County, China

Frontiers in Earth Science
The Loess Plateau is marked by intense neotectonic activity and frequent earthquakes. Its unique physico-mechanical properties, combined with the granular overhead pore structure of loess, render it prone to seismic landslides triggered by strong ...

Seismic Protection of Cabinet Stored Cultural Relics with Silicone Dampers

Shock and Vibration, 2018
Cultural relics are precious properties of all humankind, the damage of which is nonresilient. In previous earthquakes, stored cultural relics have shown poor seismic performance, so effective seismic methods are urgently needed.

Nonstationary Stochastic Simulation of Strong Ground-Motion Time Histories : Application to the Japanese Database [PDF]

, 2012
For earthquake-resistant design, engineering seismologists employ time-history analysis for nonlinear simulations. The nonstationary stochastic method previously developed by Pousse et al. (2006) has been updated.

Software engineering’s contribution to earthquake engineering

Earth Sciences Research Journal, 2013
Earthquakes are natural disasters which affect Mexico regularly. It is very important to obtain all information about them quickly, in order to speed up attention to population affected and if it is possible, applying prevention actions. At present time, to obtain knowledge of seismic events is essential to use computer and specialized software.

Earthquakes and earthquake engineering in China

Bulletin of the New Zealand Society for Earthquake Engineering, 1987
China is one of the most earthquake-prone countries in the world and has suffered many disasters. During the last twenty years, especially since the Tangshan earthquake of July 1976 which killed 242,000 people and disabled almost 200,000 people, the Chinese government and the whole society have paid more attention to and made a huge effort to deal with

Temperature‐dependent shear behavior and constitutive model of the rock–concrete interface

Deep Underground Science and Engineering, EarlyView.
Shear tests were conducted to investigate the temperature‐dependent shear behavior of the rock–concrete interface, highlighting the interaction between the surrounding rock and the lining during tunnel fires. Under experimental conditions, concrete exhibited greater temperature sensitivity than rock, with the shear fracture surface transitioning from ...

Shear behavior of bolt–grout interfaces under constant normal stiffness: Influence of grout strength and thickness

Deep Underground Science and Engineering, EarlyView.
The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

A review on rockburst prediction and prevention to shape an ontology‐based framework for better decision‐making for underground excavations

Deep Underground Science and Engineering, EarlyView.
A scientometric analysis of 2449 journal articles and a comprehensive review of 336 papers were conducted, discussing and identifying challenges and research gaps in rockburst prediction and prevention and proposing an ontology‐based framework for better decision‐making in underground excavations. Abstract With underground engineering projects becoming
