The thesis falls naturally into four parts. The first constitutes a world-wide survey of the methods used in practice to design prestressed, cement grouted rock anchors. The major topics of overall stability and system geometry, the rock-grout and grout-steel interfaces, and grout and tendon selection, are reviewed in turn. Comparisons between the standard methods of practice, and the findings from theoretical and field studies, reveal important areas of uncertainty and contradiction, particularly with regard to the mechanisms of load transfer from tendon to rock. Part 2 describes the author's full scale test anchor programme, conducted at Withnell, Lancashire, devised to investigate the major problems associated with load transfer which were highlighted in Part 1. Full details are provided of the site and its geology, and the methods of construction, testing, recording and analysis employed. Most emphasis placed on the results obtained from the fifty-seven anchors: these are fully discussed and wherever possible compared with data presented in the review. The third part deals with the long term performance of rock anchor systems. Analogous to Parts 1 and 2, one chapter is devoted to a review of relevant published information, whereas the other chapter details the author's case study of ten production anchors at H.M. Dockyard, Devonport. In Part 4, conclusions on the field test programmes are summarised and indications are given of topics meriting further research.
