| Abstract | This paper presents a displacement based back-analysis method for the determination of the elastic modulus (E), cohesive strength (C), friction angle (φ) and in situ stress of a schistose rock mass. Orthogonal experimental design (OED) method was used to design representative groups for back-analysis calculation to minimize necessary combinations. The calculated plastic convergence values were compared with in situ monitoring data. After calculation, the convergence value of a particular group fit well with the in situ monitoring deformation. The parameters of this particular group hence obtained and the set of parameters was used in underground excavation and support design subsequently. © 2012 Taylor & Francis Group, London. |
