Abstract
With the accelerating urbanization process, underground engineering has been increasingly applied in transportation, energy, and municipal construction, where shield tunneling technology plays a critical role. Optimizing this technology is of great significance for enhancing construction efficiency and safety. This study focuses on shield tunneling under complex geological conditions, aiming to propose a robust and efficient construction optimization scheme through systematic analysis and technological innovation. A combined methodology of theoretical analysis, numerical simulation, and field experiments was adopted to address key issues during shield tunneling, including cutterhead wear, surface settlement, and segment assembly accuracy. The results indicate that improved cutterhead design and the introduction of intelligent monitoring systems can significantly reduce cutterhead wear rates. Moreover, parameter-optimized ground pre-consolidation techniques effectively control surface settlement. Additionally, the newly developed synchronous grouting process enhances the quality of segment assembly and overall tunnel stability. The primary innovation of this study lies in the deep integration of intelligent technologies with traditional construction methods, forming an optimized shield tunneling system adaptable to complex geological conditions, which provides crucial theoretical support and technical references for similar projects. The final conclusion demonstrates that the proposed optimization scheme can substantially improve construction efficiency, minimize environmental impacts, and offer reliable assurance for underground infrastructure development.Key words:Shielding Construction Optimization; Complex Geological Conditions; Cutterhead Wear; Surface Settlement Control; Intelligent Monitoring System
