| Abstract: | Based upon two-dimensional finite element numerical simulation of Huangguan double-arch tunnels under unsymmetrical pressure,from stress and strain aspects the influences of two excavation methods: first excavation shallow tunnel or first excavation deep tunnel on surrounding rocks,primary support, secondary lining and mid-partition are comparatively analyzed,which provide good references for design and construction of double-arch tunnels under unsymmetrical pressure. |

| Keywords: | double-arch tunnel lateral pressure numerical simulation |
