Paper Number: ISRM-EUROCK-2016-109
... (Fig. 3). In this sense, possibility of damage by a landslide has to be evaluated. Regarding the issues summarized, slope stability analyses are needed to find out if slope failure occurs. If failure occurs, location and extent of failure plane should be specified and whether it encloses the tunnel...

... being the different shapes of failure of the samples obtained both theoretically and empirically. These shapes are mainly the following ones: In uniaxial compression nearly vertical failure planes; In triaxial compression, failure planes forming angles of 45+ψ/2 with the major principal stress, being ψ...

... bolts and concrete piers for underpinning unstable blocks. XRD analysis showed a significant amount of swelling minerals on the failure plane. Results from Odometers test corresponded to a friction angle between 10 and 15 degrees. The final support included 25 rock anchors each on 200 tons and removal...

... not depend upon the location of the plug. It is also confirmed that a failure plane can appear in the area on which the confining normal pressure is acting. A sliding analysis is carried out for the experimental conditions. From a comparison of the experimental and the calculated results, the applicability...

... by the stresses on the failure plane, is stablished depending on dilatancy. The values proposed by Hoek and Brown (1977) are adopted for the angle of dilatancy. These hypotheses are applied to some simplified cases for volcanic materials, and different charts are obtained that associate the slope height and slope...
