The rock masses comprising the slope at the portal of a twin-arched tunnel in the town of Fuxi, Anhui province are strongly affected by weathering and unloading. Before excavation, the slope had noticeable down-slope deformation at its middle and upper levels and the deofrmation was in the state of limit equilibrium. On the basis of the site investigation and the study of the rock mass structures, the paper esbalishes the deformation mode and failure mechanism of the slope. Furthermore, the… Expand
