Vibration Response Characteristics and Emotional Risk Assessment of Tunnel Blasting Construction with Intelligent Safety Protection Measures
Yuan ZhangAbstract
Objective
Strong tunnel blasting vibration and unpredictable on-site safety hazards bring long-term cumulative psychological pressure to front-line construction workers, easily inducing persistent emotional anxiety and turbulent mental states, which adversely affect individual mental health, working enthusiasm and overall construction efficiency. This study systematically analyzes the vibration response characteristics of tunnel blasting under intelligent safety protection conditions and evaluates on-site personnel’s emotional risks, aiming to effectively alleviate construction-related psychological pressure and comprehensively improve workers’ occupational mental health level.
Subjects and Methods
Taking front-line tunnel blasting construction workers as the core research objects, this study adopts field vibration monitoring, finite element numerical simulation and standardized psychological questionnaire measurement methods. It effectively obtains real-time blasting vibration data under intelligent protection conditions, and statistically explores the internal correlation between vibration stimulation intensity, personnel psychological pressure fluctuation and dynamic mental health changes.
Results
Adopted intelligent safety protection measures can effectively suppress tunnel blasting vibration responses and reduce harsh environmental stimulation. The optimized and safer construction environment significantly relieves workers’ chronic psychological pressure, calms negative and tense mental states caused by long-term safety worries, and achieves prominent improvement in individual mental health status and on-site emotional stability.
Conclusions
Matched intelligent protection technologies can effectively control tunnel blasting vibration and safety risks. Scientific emotional risk assessment helps timely intervene in construction psychological pressure, adjust abnormal mental states, stabilize workers’ good mental health conditions, and provide reliable practical references for integrating engineering safety construction management with on-site staff mental health protection.
