Abstract

Abstract

This paper relies on the shield construction of the crossing tunnel in Sichuan university West campus in Chengdu.Through monitoring the deformation of road above the crossing tunnel and metro tunnel below;and combining with the finite element numerical simulation to simulate the shield tunnel construction process of crossing tunnel by 3D-FEM;combined with field measurement results comparative analysis and impact assessment are carried out.
