Screw-Piles Helical Anchors Soils This Guide should be used for preliminary calculations only and applies only to the deep installation of Screw-Piles and Helical Anchors in uniform soils. It is only applicable for design when the depth (D) to the top helical plate is greater than 10 times the diameter (B) of the helical plate…
Incercari de penetrometrie dinamica Calcularea valorii N60 Corelatiile recente pentru NSPT, densitate relativa si unghi de rezistenta la forfecare pentru terenurile granulare sunt prevazute cu valori ale rezistentei penetrometrice in functie de N60 (NSPT=N60 dupa Cestari, 1996) sau N1,60 valoare normalizata la o tensiune geostatica verticala de 1 bar prin aplicarea coeficientului CN (Liao Withman…
