The article contains experience in strengthening critical large-cast reinforced concrete monolith structures under heavy-load conditions on the operating construction enterprise. Herewith measures aimed to strengthen reinforced concrete loading ramp retaining wall resulted in the change of operation scheme as flagstone with outline abutment to classic operation scheme of retaining wall with reverse transom. All the main stages of the strengthening process technique are described in detail, in particular starting from the examination stage of the structure mode of deformation, its monitoring during implementation of works, and ending with stage of exploitation of both reinforced concrete technological foundations and retaining wall under operational loadings.
