Abstract

State-of-the-Art, Tunnel Engineering in Mainland China

This report presents the research progress in tunnel engineering, including construction methodologies, fundamental theories, auxiliary techniques, equipment development, and operation and maintenance in China, with case studies of large tunnel projects. Key aspects include: (1) ‌Construction methods‌: Evolution of China’s shallow buried tunneling method. (2) ‌Fundamental theories‌: Novel theories on soil-water pressure accounting for ground deformation, support structure stiffness design, loess tunnel support, active-yielding support for high-stress soft rock, and other extreme-environmental support systems. (3) ‌Mountain tunneling‌: Stability control of fault zones, soft rock large deformation, and hard rock rockburst, with innovations in coordinated deformation support. (4) ‌Urban tunneling auxiliary measures‌: Displacement control for shield tunnels crossing existing structures and safety measures for weak/mixed strata. (5) ‌Intelligentization‌: AI-driven unmanned shield tunnelling and smart construction of steel-shell concrete immersed tube tunnels. (6) ‌Green construction‌: Eco-friendly muck treatment and resource recovery technologies for urban tunnels. (7) Equipment innovations: World’s largest combined rectangular pipe jacking machine, shield main bearings for shield machines, adaptive shield machines, and shield innovations in extremely complicate environments. (8) ‌Operation and maintenance: Lifecycle monitoring of prefabricated metro stations, AI-based disease detection, and grouting lifting techniques. (9) ‌Case studies‌: Technological breakthroughs in super tunnel projects, demonstrating China’s development in tunnel engineering.
