ABSTRACT
The paper presents the technical solution adopted in order to protect and ensure the stability of tall buildings in the city of Deva, next to which a subterranean road passage and underground parking place are realized. The technical solution was determined based on detailed studies concerning the geological and geotechnical conditions of the locations of the two underground units. Also, the depths of the diggings, the height and foundation levels of the neighboring buildings including the distances from the edges of the diggings have been analyzed. The adopted technical solution consisted in realizing supporting walls on the contour of the diggings. The walls were made up of large diameter piles placed tangentially through drilling.
