Abstract: [cze] [eng]
Odvození vztahů mezi polodélkou podélné průchozí trhliny v tlakovémmpotrubí a výtokovými parametry vody při reparačním přetížení potrubívnitřním tlakem vody. Výsledky jsou ukázány u části potrubí o délce1680 m, zhotoveného z ocelových trubek o průměru 530 mm a tloušťcestěny 6 mm. Derivation of relations between the half-length of a longitudinalthrough crack in a pressure linepipe and outflow parameters of wateras followed from reparation overloading of linepipes by internalpressure of water. The results are demonstrated on a specific pipelinesection 1680 m long, made from steel pipes 530 mm in outside diameterand 6 mm in wall thickness.
