Impact and Safety Assessment of a Double-Tube Parallel Tunnel Excavation on Adjacent Pipelines

Abstract:

The interaction of a double-tube parallel tunnel excavation will have a larger additional shearing action on the adjacent pipelines. This paper, taking 202 Section of Line 2 on Dalian Metro as the background, uses the finite difference software to establish 3-D finite element analysismodel to simulate the double-tube parallel tunnel excavation. Deformation of adjacent pipelines is analyzed specially by numerical simulation of tunnel excavation and also the safety of the pipelines is forecasted. The conclusions and advices are important to design and guide the actual project construction safety.
