Investigation of Asymmetric Failure Mechanism in Perforated Soft Rock Under Coupled Dynamic–Static Loads: Multiscale Insights into Cavity-Induced Dynamic Responses

Key Points

• Asymmetric failure mechanism governs dynamic responses in perforated soft rock under loads, highlighting structural vulnerabilities.
• Key findings indicate that dynamic responses can vary significantly due to cavity effects within the rock.
• Multiscale insights explore the influence of coupled dynamic-static loads on failure mechanisms in soft rock formations.
• This work suggests that understanding these mechanisms could improve safety and design in geotechnical engineering applications.
