Abstract
With the accelerating urbanization process, deep excavation projects are increasingly common in high-rise building construction and underground space development, making the design and construction technology of retaining structures a critical factor for ensuring project safety and the stability of the surrounding environment. This study focuses on deep excavation projects under complex geological conditions, aiming to explore design methods for retaining structures suitable for different types of strata and to optimize construction techniques. By integrating theoretical analysis, numerical simulation, and field monitoring, a systematic evaluation of various retaining forms was conducted with respect to their performance in force characteristics, deformation control, and stability. The results indicate that a deep excavation design scheme based on an improved anchor support system can significantly enhance the load-bearing capacity of retaining structures while effectively reducing the horizontal displacement of the enclosure structure. Furthermore, a dynamic adjustment strategy incorporating real-time monitoring data is proposed, providing a scientific basis for risk control during the construction process. The innovation of this study lies in integrating geological conditions, construction techniques, and monitoring feedback into an integrated design fr amework, offering a referable technical approach for similar projects and contributing significantly to the advancement of deep excavation engineering technology.Key words:Deep Excavation Engineering; Supporting Structure Design; Improved Anchorage; Dynamic Adjustment Strategy; Complex Geological Conditions
