Resum
A 100 m high gravity dam (Castrovido dam, Burgos, Spain) is founded on a soft Weald red claystone with inter-bedded sandstone strata. Claystone weathering was identified in vertical and horizontal profiles of water content and dry density. Peak and residual strength of rock matrix is given in the paper. Clay and sandstone layers dip 15–20 in the upstream direction. Dam stability is essentially controlled by the available shear strength at the sedimentation planes. Block samples were recovered ...
