A case study on construction method of four-line tunnel in weak rock
Abstract: In China, there is a railway station extended into a tunnel with 547m, which located in secondary line from Liupanshui to Zhanyi. So a large span tunnel with four lines formed. Its largest excavation span reaches 28.42m, and the maximum cross-section area is 354.30m. This paper took this case studied. It is suggested to divide the tunnel to three sections as portal section, shallow buried...

Numerical simulation of the mechanical behavior of cobble rock mass during tunneling using granular discrete element...
Abstract: The study mainly discusses the mechanical behavior of cobble rock mass during tunneling in Chengdu metro line 1. Cobble rock mass could be regarded as an assembly of discrete particles with the micro parameters of the rock mass have a significant impact on its macro mechanical behavior. Due to the characteristic of such rock mass, conventional study method in continuous medium is no longer...
