Safety Analysis of Super Long Span Viaduct Crossing Existing Tunnel during Construction
During the construction of multi-storey viaduct,there will be great potential safety hazards for the existing tunnels in the lower layer.In this paper,taking the construction of a super long span steel box girder viaduct crossing an existing tunnel as an example,the construction process of the steel box girder is simulated and analyzed by using the three-dimensional space finite element method and the birth death element technology,and the safety analysis of the finite element calculation results and monitoring data is carried out,which can provide a reference for the safety evaluation and protection of similar projects.
