Abstract:

This paper does not deal with the usual rockfalls during tunnel heading but only with those which occurred afterwards during the operation of pressure galleries at various power plants, and which resulted from the decomposition of the fissure filling and from the local disintegration of the rock structure under the influence of the varying water pressure, when the gallery water gained access to the rock.
