The advantages of the tunnel boring method primarily include reduced ground settlement, minimized impact on surrounding structures, no constraints from surface conditions, suitability for deep excavations and construction under high groundwater pressure, relatively lower costs, high construction efficiency, advanced automation and智能化 features, and significantly lower labor intensity.
The shield method, as a fully mechanized construction technique, offers the following significant advantages:
Reducing ground settlement and its impact on surrounding structures: The shield method effectively prevents ground collapse by supporting the surrounding rock mass through the shield shell and segment lining, thereby minimizing ground settlement and reducing the associated risks to nearby structures.
Unrestricted by surface conditions: Shield tunneling is not limited by topographical, geomorphological, or fluvial features of the ground surface, making it suitable for tunnel construction in a wide range of complex geological conditions.
Suitable for construction in deep tunnels and under high groundwater pressure: The shield tunneling method is ideal for environments with significant depth and intense groundwater pressure, offering relatively lower construction costs compared to other methods.
Costs are relatively low, and construction efficiency is high: Shield tunneling offers significantly higher construction efficiency, and over the long term, its cost-effectiveness becomes increasingly evident, giving it a distinct cost advantage compared to other construction methods.
Highly automated and intelligent, with low labor intensity: Operations such as shield tunneling propulsion, muck removal, and segment assembly can be fully automated and智能化, enabling rapid excavation while significantly reducing construction labor intensity.
These advantages have made the shield method one of the widely adopted techniques in modern tunnel construction, particularly playing a crucial role in urban underground space development and large-scale infrastructure projects.
