Paper presented at the ISRM International Symposium - EUROCK 2016, August 29–31, 2016
Paper Number: ISRM-EUROCK-2016-186
... laboratory tests and in situ tests. 1 INTRODUCTION Intense tectonic deformations can result in a pervasive shearing of the rock mass. Typically, a shear zone is characterized by a complex network of important discontinuities, which can interact with large engineering works, such as dam foundations...

Paper Number: ISRM-EUROCK-2016-185
... ABSTRACT: The geotechnical characterization of a rock mass is a process that involves the evaluation, selection and synthesis of different nature information, the methodology illustrated here is an example developed for a dam foundation that integrates experimental and empirical approaches...

Paper presented at the ISRM Regional Symposium - EUROCK 2014, May 27–29, 2014
Paper Number: ISRM-EUROCK-2014-003
... Abstract The application of discontinuum idealizations to the analysis of dam foundations is addressed. The options for the representation of the rock mass discontinuities are discussed, from the perspective of assessing failure modes involving the rock mass. An example of concrete gravity dam...

... filling, initiated an erosion process that led to the complete removal of the dam's foundations central portion and the struc-ture in consequence becoming supported only on its abutments. Numerical nonlinear tridimensional flow analyses have shown that the water velocities in the vertical open joints were...

Paper Number: ISRM-EUROCK-2002-078
... Concrete plug replacement is a treatment method for faults in concrete gravity dam foundations. To investigate the effects of concrete plug installation on the shear strength of dam foundations, direct shear tests are carried out for rock models made of plaster. From the experimental results...

... ABSTRACT: A mathematical model for simulating the interaction between underground water flow and mechanical behaviour of the system is used for Izvorul Muntelui concrete dam case. This dam with 126 m maximum height was comissioned in 1961. The data concerning uplift pressures on dam foundation...
