Comparative Analysis of Shallow-Buried Unsymmetrically-Loaded Tunnel Construction Scheme
With the rapid development of road and infrastructure construction,tunnel engineering plays an increasingly important role in passing through complex terrain and overcoming the problems of high fill and deep excavation.Taking the Xiongzi Tunnel as an example,this paper analyzes the change law of tunnel displacement under different excavation schemes,and finds that the tunnel that is excavated first has a larger vault sinking and inverted arch uplift due to the long deformation time,and provides on-site construction suggestions to provide a reference for the construction of such shallow-buried unsymmetrically-loaded tunnels.
