Abstract
AbstractAnchored retaining structures demand detailed preliminary investigations for appropriate and economic repair and upgrading. However, due to the complex constraints and insufficient data basis, it is often necessary to investigate the basis for the design of repair works in advance. The article described two anchored constructions. The first is a bored pile wall to dowel a slope. In addition to the repair of corrosion damage to the strand anchors, repair of the uphill drainage system is an essential part of the refurbishment concept. The second example is a retaining structure about 40 years old, in which several rod anchors show corrosion to their heads. Since there is a lack of information about the ground conditions for the assessment of structural safety and design of repair works, additional investigation boreholes were drilled.
