Prediction of Collapse Scope of Deep-Buried Tunnels Using Pressure Arch Theory [PDF]
Mathematical Problems in Engineering, 2016 Tunnel collapse remains a serious problem in practice. Effective prediction methods on tunnel collapse are necessary for tunnel engineering. In this study, systematic study on the pressure arch was presented to predict tunnel collapse. Multiple factors under different conditions were considered. First, the pressure arch was described as a certain scope
