Taken the 202 section of Dalian Metro, Xianggong street station to Shahekou railway station, as an example, the H-M coupled numerical simulation was realized by using program in FISH language. The deformation and failure characteristics of excavation face and surrounding rock during tunnel excavation were analyzed. The stability of excavation face was further evaluated according to numerical results of ZSI. The results indicate that the proposed method can be used to well simulate and analyze the H-M coupling process, which are in good agreement with measured results.]]> Mon 04 Feb 2019 15:02:09 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32079 3D as the basis and by introducing the zone state index (ZSI) into the volumetric strain, the relationship between ZSI and permeability is established. Numerical simulations are conducted to verify experimental results by adopting a nonlinear creep Nishihara model based on the strain softening. The results show that the permeability along with the development of the time in the process of loading near the inlet side of the permeability changes quickly. The damaged area of ZSI contours is coincided basically with the failure mode of the test samples in the "V"-typed shear zone. The theoretical curves are in good agreement with the numerical ones. The proposed model can reflect the creep-seepage coupling characteristics and the local failure rules of rock under loading-unloading conditions.]]> Fri 27 Apr 2018 13:30:56 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46600 Fri 25 Nov 2022 15:31:22 AEDT ]]>
