Resum
A 100 m high gravity dam (Castrovido dam, Burgos, Spain) is founded on a soft Weald red siltstone with interbedded sandstone strata. Dam stability is essentially controlled by the available shear strength of sedimentation planes. Block samples were recovered for the different types of contact identified. They were tested in high capacity shear box machine (30x30 cm) and in large scale shear tests. The roughness of the sheared plane was determined after each one of the tests. Additional informati...
