Over the last years, an increase of damages and defects of geotechnical
structures has been observed during detailed safety
assessments. This is mostly related to the rising age of these
structures and the related decrease of the bearing capacity.
The handling and dealing with these existing structures will be a
challenging task for future civil engineers. This article should give
an insight into damages and defects of retaining structures,
which are quite difficult to detect and evaluate in terms of safety
and risk. The first part of the article gives a short overview on the
state of the art when it comes to the safety assessment of existing
retaining structures and introduces a new, currently being
edited, ÖGG guideline for this field of civil engineering. The
part deals with corrosion-induced damages on cantilever
walls and shows first results of the research project SIBS (safety
assessment of existing retaining structures).
