Analysis of Effects of a Double-Tube Parallel Tunnel Excavation on Underground Pipelines

Abstract:

The interaction of a double-tube parallel tunnel excavation will greatly influence on underground pipeline of its region. This paper, taking Dalian Spring Street subway station as the background, uses the finite difference software to establish 3-D finite element analysis model to simulate the effects of tunnel excavation on underground pipeline, in which different embedment, material properties and diameters are considered. By analyzing of the settlement and deformation law of pipeline, the least affected pipeline conditions are drawn to provide corresponding guidance for subsequent underground projects.
