Abstract

After the failure of a cantilever retaining wall with counterfort on the Brenner Autobahn, intensive investigation of existing structures showed considerable corrosion damage to cantilever walls with and without counterforts, at the location of construction and day joints. This is difficult to detect and assess due to the placing of the main reinforcement at the back of the construction. The present paper presents a monitoring concept, which enables detection of corrosion damage and also provides a gain of information about the behaviour of the structure. The basis for this concept is the installation of inclination and strain gauges on the front of a retaining wall. In order to explain the functioning of the concept, a rudimentary cantilever model of the effect of corrosion damage is first described. Then the results and findings from a test series with artificial corrosion representation to reinforced concrete structures to validate the presented monitoring concept is described.
