6 FAQs about [High solar container rock mass excavation]
Are high-stress brittle rock masses damaged during excavation at Shuangjiangkou underground caverns?This study reports detailed findings from an exhaustive investigation on the damage characteristics and underlying mechanisms in the high-stress brittle surrounding rock masses during excavation at the Shuangjiangkou (SJK) underground caverns.
Can brittle rock masses be identified by high-stress excavation?These research findings are poised to provide valuable insights into the damage identification of brittle surrounding rock masses subjected to high-stress excavation, contributing to optimize excavation design and enhance the safety and sustainability of underground engineering projects. 1. Introduction
What is the energy evolution of rock mass during deep tunnel excavation?The general process of spatio-temporal energy evolution of rock mass during deep tunnel excavation was revealed. Continuous excavation in deep tunnels generally involves an energy accumulation process (a SED peak) and two energy release processes (two EDR peaks).
How does pilot tunnel excavation affect the energy evolution of rock mass?Figure 22 provides a more intuitive picture of the effects of pilot tunnel excavation on the energy evolution of rock mass. Obviously, after the secondary excavation of the main tunnel, the energy level of surrounding rock within the length range of pilot tunnel is significantly reduced, and the stability is significantly improved.
Can excavation-induced damage be measured in high-stress brittle rock masses?This consistency validates that the newly proposed damage index has good applicability and reliability for quantifying excavation-induced damage in high-stress brittle surrounding rock masses.
How does excavation affect underground caverns?Excavation-induced damage in the surrounding rock mass of underground caverns is primarily manifested through the formation of new stress-induced fractures.

Evolution mechanisms of stress-induced disasters in deep hard rock excavations, such as spalling, deep cracking, massive roof collapse, large deformation and rockbursts, have been
Blasting excavation induced damage of surrounding rock masses in
The damage induced by the blasting load and the transient unloading of the excavation load in surrounding rocks should not be ignored during the excavation process of deep-buried tunnels
Excavation damage of surrounding rock of deep high-temperature
The high-stress and high-temperature issues of deep engineering pose significant challenges to deep resource exploitation and underground space utilization. By establishing a
Weakening laws of rock mass properties in blasting excavation
<p>The weakening of rock mass properties caused by blasting excavation has an adverse effect on slope stability. The Hoek-Brown (H-B) criterion is one of the effective approaches to quickly estimate
Numerical analysis on dynamic response and damage threshold
The excessive destruction of surrounding rock in deep tunnel will change the original environmental state and destroy the natural ecological balance. Research on the dynamic response characteristics
Excavation-induced deep hard rock fracturing: Methodology and
To analyze and predict the mechanical behaviors of deep hard rocks, some key issues concerning rock fracturing mechanics for deep hard rock excavations are discussed. First, a series of
Mechanical Behavior and Energy Evolution of Surrounding Rock
This study focuses on the mechanical characteristics of the surrounding rock and the energy evolution mechanism during the unloading process of high-stress rock mass excavation.
