Effect of EPB Shield Tunneling on Adjacent High Speed Railway Viaduct

Abstract:

Based on a project of subway constructed near elevated high speed railway, FEM method is adopted to analyze the effect of shield tunneling on the horizontal and vertical displacement of pile foundation of the viaduct as well as the pile caps on the condition that the nearest clear distance is 5m. The results show that with appropriate parameter control of shield tunneling, the effect of EPB shield tunneling on the displacement of piles in the three directions, i.e. horizontal displacement along and perpendicular to the longitudinal direction of the rail line and vertical displacement, is little. The same goes for the differential settlement between pile caps.
