Clunie Dam Anchoring Works

摘要

Following the statutory inspection of the Loch Tummel reservoir "matters in the interest of safety" were raised requiring a stability analysis be carried out to check the behaviour of the dam under load from a Probable Maximum Flood (PMF) event and also from a seismic event.rnThe paper describes the analysis; site investigation; subsequent design; and on-site construction works to implement a dam anchoring scheme which meets the requirements of the Qualified Civil Engineer.rnThe analysis and subsequent works carried out to Clunie Dam were required following the 10-yearly statutory inspection under the Reservoirs Act 1975 which was carried out in June 1999 by Dr A K Hughes. Subsequent structural assessments demonstrated that the seismic stability of the dam was adequate, but that under worst case PMF conditions, the abutment sections of the dam were likely to crack becoming grossly unstable and were expected to fail. Further consequence studies and ALARP studies demonstrated justification for implementing strengthening works.
