Analysis of the Influence of Metro Tunneling on Building Settlement
Abstract: Although the characteristics of ground settlement without buildings have been defined, but further research is still needed for the characteristics of settlement with buildings, and such research has more theoretical significance and engineering application value. Targeting at the specific strata and shallow foundation buildings, FLAC 3D is utilized to establish the three-dimensional numerical...

Harmful Gas Eruption Prediction and Its Protection Based on Solid-Fluid-Gas Coupling in Shield Tunneling
Abstract: In some cities in southern China, the shield machine will be encountered the geological environment of explosive harmful gas in the process of metro tunneling, combined with the shield machine does not have explosion-proof function, that is likely to cause harmful gases gush out in a moment and induce harmful gas exceed standard even explode. Therefore, solid-fluid-gas coupling theoretical...

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...

Robust Design Method of Large-diameter Shield Tunnels through Multiple Strata
Abstract: Since the large-diameter shield tunnel usually goes through multiple strata, the variation of ground condition may have a very significant impact on the tunnel performance. Unfortunately, the conventional design method cannot consider the effect of uncertainty of the multiple strata. Thus, the robustness design method of large-diameter shield tunnelling through multiple strata is proposed. The...

The Analysis of Excavation Sequence Effect of Overlapped Shield Tunnel in Sandy Cobble Ground
Abstract: The mechanical behavior of the overlapped region of shield tunnel in the sandy cobble ground is complicated, which differs from other constructing ways under common geological conditions. Combined with the construction of overlapped shield tunnel in the Baicao Road interval of Chengdu second Metro, the 3-D finite difference model was built. The overlapped tunnels mainly go through...
