In order to analysis the feasibility of cancelling setting invert, 3 kinds of models are set as following: Model 1: ordinary flat-bottom tunnel model Model 2: inverted tunnel model Model 3: flat-bottomed tunnel (Grouting bolts bellow the tunnel and pouring C25 concrete on the bottom tunnel where digs out 20cm-thickness original rock) Surrounding rock uses HowkBrown models, and the remaining material uses a linear elastic constitutive relation.
