Abstract

The Paper describes failures of some high tensile strength steel tensioned rock anchors at a deep excavation. The failures are attributed to stress corrosion to which the high tensile strength steel is particularly susceptible. The method which was used to estimate the life of remaining anchors on the project is described. The need for ensuring a high level of care during transportation, storage and installation of such high tensile strength steel bars is emphasised.
