Figure 14From: Hydraulic fracturing and its peculiaritiesHorizontal displacement of the dam crest versus time. No fracture at all (elastic); dry fracture (fracture), i.e. water pressure acts only on the dam, not on the crack lips; hydrostatic water pressure in the crack, constant over the crack length (hydraulic fracture); and fully coupled solution with water pressure varying over the crack length and fluid exchange between the crack and surroundings (u- p).Back to article page
