| Abstract: | Based on the features of the parallel tunnels with shallow overburden,the yielded region,ground deformation that are influenced by the excavation of the twin tunnels,and the stability of rock between the twin tunnels are analyzed.Meanwhile,the rock deformation and inner force of the support induced by the construction of twin tunnels by turns,it provide insight to the arch settlement that induced by the bench construction. |
