LIMIT DEFORMATIONS OF RETAINING WALLS IN LITHUANIAN HYDROSCHEMES

In accordance with Standard STR 2.05.04: 2003 all deformations of hydraulic structures are divided in two groups: 1) main - deformations of whole structure and 2) local - deformations of joints, supports, etc. Retaining walls of the used hydraulic structures are under the influence of climatic conditions, water, soil pressure and other types of loads. Deformations appear because of the aggressive environment and the load influence. The aim of the work is to evaluate the limit deformation of retaining walls on hydroschemes. The state of 14 reinforced concrete retaining walls of hydroschemes was evaluated during the scientific expedition in the period 2007-2012. Retaining walls of hydraulic structures in Kaunas, Marijampole, Kedainiai, Panevezys, Silute districts were examined and main deformations were determined.
