Analysis of the Mechanical Property of Collapse in Shallow-Buried Loess Tunnel under Unsymmetrical Pressure
Based on selecting a tunnel collapse under typical conditions of the shallow-buried terrain under unsymmetrical pressure, analyzing the monitoring measurement date, using the software of finite element numerical simulation, the paper simulates the tunnel excavation in lengthwise, deduces the change laws of stress in primary support, the mechanical properties and the collapse mechanism.
