A Preliminary Study on the Comprehensive Evaluation of the Disaster Prevention System of Large Urban Underground Space
Abstract: Urban underground space has been explored and used as basement, passageway, metro tun-nel and parking garage for a long time. The development of relatively shallow underground space is the primary stage, during which the mentioned underground structures are relatively small in scale, span length and depth. People usually go into these places only for passing by, they don’t like to stay in these...

Field study on tunnel lining resilience under extreme surcharge
Abstract: The rail transit (metro) system in metropolis is one of the best solutions to relieve the congested transportation pressures. In Shanghai, the metro system with a 538km of mileage takes up 43% of daily public transportation volume. In operating such a huge system, the safety of tunnel lining structures subjected to any unexpected hazards is badly concerned by the government and the engineers....

Numerical modeling of the seepage erosion process around tunnels using DEM
Abstract: For a shield driven tunnel with segmental lining built in saturated soils, the tunnel convergence and differential longitudinal settlement may induce the opening and stagger of segmental joints and generate segmental cracks. Therefore, the leakage frequently happens at the locations such as the circumferential and longitudinal segmental joints, cracks and grouting holes. In the low permeability...
