Investigation of deformation of existing tunnel due to above excavation unloading considering tunnel lateral response

Abstract The safety of underlying metro tunnels is significantly compromised when the excavation of the overlying foundation pit is not properly conducted. Currently, research on the longitudinal deformation of tunnels induced by upper excavation typically relies on the Pasternak model, which assume...
