RISStudy of Stability of Surrounding Rock due to the Approach of Two Excavation Faces and Face Reinforcement in a Large Cross-Section Tunnel in Weak Stratum
Publisher: American Society of Civil Engineers
Abstract: When the two excavation faces of a tunnel constructed from both the entrance and exit simultaneously in soft surrounding rock approach, the excavation surface disturbance areas are superimposed, stress and deformation in ...
Research on Pre-Reinforced Regions and Strength Parameters of Shallow Tunnels in Weak Strata
Publisher: American Society of Civil Engineers
Abstract: Safety coefficient and surface settlement were chosen as evaluation indictors for non-self-stabilizing weak strata and basic self-stabilizing weak strata. Fluid mechanical interaction is used to analyze the pre-reinforcement ...
