Abstract: The simulation models of two typical supporting structures has been established, according to the structure characteristic of X supporting and horizontal supporting, which analyzed the simulation models of different contact areas with class II and class V rock. The results show that class II rock remains stable only in 100% contact area while class V rock is difficult to maintain stable when using horizontal supporting structure. Class II and class V rock both can remain stable under X supporting structure. The above analysis conclusions will provide a theoretical basis for TBM supporting structure selection in the future.

Key words: TBM, horizontal supporting structure, X supporting structure, LSDYNA, surrounding rock stability
