| Abstract: | It is unreasonable to study the large deformation of soft rock with classic linear deformation theory. In this paper it is stated that the right analysis way of soft rock large deformation should use the finite deformation mechanics. Based on the finite deformation mechanics, an engineering case analysis is given to simulate the failure mechanism and the process of large deformation of the soft surrounding rock of the roadway by using FLAC technique. |
