The Sri Lankan Rock Mechanics and Engineering Society (SLRMES) along with the Peruvian Society of Geoengineering (SPEG) invite you to participate in the First ISRM Commission Conference on Estimation of Rock Mass Strength and Deformability to be held in Lima, Peru on December 6, 2024. The main purpose of the conference is to establish the current status of the procedures available to estimate rock mass strength and deformability.

Most naturally occurring discontinuous rock masses comprise intact rock interspaced with different types of discontinuities. Fissures, fractures, joints, faults, bedding planes, folds, shear zones, and dykes are different types of discontinuities that exist in rock masses. Discontinuities may be divided into major and minor using the feature size. Large features may be considered as major discontinuities, and the rest of the small features may be considered as minor discontinuities. For most of the civil and mining engineering projects, at the uppermost level (for the domain size considered for analysis), rock masses contain only a few major discontinuities. For such rock engineering projects, major discontinuities may be considered as single features, and their geometry may be represented deterministically. On the other hand, due to their large number and inherent statistical nature, the geometry of minor discontinuities should be characterized probabilistically.
