	The digging of one or more tunnels is a process that destabilizes the field, maintaining the stability of the tunnel wall and



	control of ground movements around the gallery resulting from each excavation and the interaction between two tunnels mu

	tunnels throughout the spatial configurations and evaluated the ground motion induced by the interaction between



	these two

	. Th

	situ measurements was



	established in the particular case of two parallel horizontal tubes of the tunnel T4 on Elharouche Skikda and for which



	experimental data exist.
