, Num1A et Num2A, les vitesses de passage par l'écran EC11 semblentêtre proches de celles que l'on avait avant décalage de la zone de départ. En moyenne
, Concernant le Bloc Num1A, nous avons uneénergie totale moyenne de passage par l'écran EC11égaleà 11, vol.35
, 40 kJ (Tableau C.1(b)). Nous concluons ainsi que, en termes de vitesse et d'énergie de passage des blocs, la modification de la position de départ semble avoir une importance moindre que celle constatée sur les trajectoires
En moyenne, les valeurs de vitesses ont subi un changement significatif. On note, pour le Bloc Num2A, une vitesse de passage par l'écran EC12 de 4.98 m/s contre 6.54 m/s auparavant. Pour le Bloc Num1A, vol.12, p.55 ,
, En revanche, les distances de propagation sont plus importantes, ce qui témoigne de l'effet important que peut avoir un changement de topographie en partie basse du profil. De plus, ces distances sont liées aux valeurs d'énergie de passage maximales qui sont plusélevées, Nous avons donc des valeurs moyennes de vitesse de passage plus faibles
, En revanche, le Bloc Num1A franchit l'écran EC12 avec une vitesse plusélevée, avec une valeur maximale de 7.85 m (contre 5.82 m avant décalage). Il semblerait donc que le décalage de la zone de lâchers induise une augmentation de la vitesse et de la hauteur de passage qui est de l'ordre de 2 m pour l'écran EC12 et une diminution des hauteurs de passage par EC11 de l'ordre de 60 cm
