Underground Infrastructure Resilience
Research Guide
What is Underground Infrastructure Resilience?
Underground Infrastructure Resilience refers to strategies and technologies enhancing underground systems like tunnels and metros against seismic events, flooding, and disasters through risk assessment and retrofitting.
This subtopic focuses on resilience frameworks for tunnels in alluvial deposits (Huang et al., 2022, 110 citations) and flood risk models for metro systems (Wang et al., 2021, 56 citations). Sponge City practices integrate underground resilience for urban water management (Zevenbergen et al., 2018, 153 citations; Yin et al., 2022, 71 citations). Over 20 papers from 2010-2024 address seismic response and disaster prevention benefits.
Why It Matters
Resilience models reduce urban flood damage in metros, as shown in Guangzhou case studies using fuzzy AHP (Wang et al., 2021). Tunnel assessments under seismic hazards guide retrofits in alluvial areas, minimizing economic losses (Huang et al., 2022). Sponge City transitions enhance underground flood capacity, protecting populations in China (Zevenbergen et al., 2018; Liu et al., 2021). These approaches support sustainable urban development amid rising disasters (Peng et al., 2021).
Key Research Challenges
Seismic Vulnerability Assessment
Tunnels in alluvial deposits face complex dynamic responses to Rayleigh waves, complicating resilience frameworks (Huang et al., 2022; Li et al., 2010). Accurate modeling requires integrating soil-structure interactions under earthquakes. Standardization of assessment methods remains inconsistent across regions.
Urban Flood Risk Modeling
Metro systems demand precise flood risk evaluation using trapezoidal fuzzy AHP, challenged by data scarcity in real-time scenarios (Wang et al., 2021). Integrating underground space with surface flooding adds uncertainty. Validation against historical events like Guangzhou floods is limited.
Retrofit Implementation Barriers
Transitioning to resilient designs like Sponge Cities faces policy and technological hurdles in China (Zevenbergen et al., 2018). Post-disaster reconstruction decisions for horizontal infrastructure delay recovery (MacAskill, 2014). Balancing cost with long-term durability hinders widespread adoption.
