.... INTRODUCTION Several conceptual models are found in the literature to elucidate gravitational mass movements (landslides). Varnes (1978) presented around thirty types. Cruden & Varnes (1996) continued developing the classification. Hungr et al. (2014) made an update from previous studies, introduced...

... ABSTRACT: RMR and SMR are two of the most applied classifications for tunnels and slopes, respectively, excavated in rock masses. Five parameters are used to compute the basic RMR classification for each discontinuity set. However, it is not clarified the whole Rock Mass RMR value. Here...

... ABSTRACT: The most common rock mass classification systems have been developed around hard rocks and do not fully apply to the characterization of weak rocks. Moreover, fault carbonate rocks present unique properties that cannot be accounted for when using these systems. Therefore, a new...

... then analyze measures to reduce dislocations and review existing fundamental conclusions on fault prevention. Preliminary results on the staggered classification of active faults have been obtained through a literature analysis. Anti-fracture measures that might be applied to the railway were identified...

... ABSTRACT: Classifying rock masses implies a systematic quantification of various field data, lately including point clouds acquired using LiDAR or photogrammetric techniques. They have been proven useful for extraction of additional information and more confident rock mass classification...

... ABSTRACT: Dozens of rock mass classification systems (RMCS) have been developed since the 1950s for applications like tunnelling, mining or rock slopes. The abundance of systems and ongoing discussions amongst scholars and practitioners are symptomatic of the complexity of the problem and show...

... ABSTRACT: The empirical method has been traditionally used for the design of permanent rock support in hard rock tunnels. Engineering classification systems have typically assisted empirical design with the description and classification of rock masses, together with recommendation...

... ABSTRACT: Rock mass characterization has a high degree of uncertainty due to difficulties in capturing the heterogeneity of the rock mass, and due to human subjectivity and biases while mapping. Since classification systems are often used as a tool to decide rock support design...

... ABSTRACT: Geomechanical classifications have been used for the analysis of tunnels and mines since the 1970's. The database generated is huge: all types of lithologies, countries and works. However, there are few studies on its application to caves. The geotechnical stability of natural...
