Stability Assessment Of Dartmouth Dam Crest Road

N. D. Benson

This paper describes a case study where the AGS guidelines on Landslip Risk Management were utilised as part of a stability assessment undertaken by Golder Associates Pty Ltd for VicRoads at a site on the Dartmouth Dam Crest Road, located west of Dartmouth Village in North East Victoria. A previous investigation by others had recommended costly engineering works involving significant buttressing and rock anchoring work in a difficult and potentially dangerous environment. These recommendations were based on a subjective assessment. The objective of our work was to review and assess the available information, undertake a walkover survey and provide advice on the need and timing of remedial actions at the site. Advice was also required by the client on the relative risk that the site provides, options for action, and the relative urgency of such remedial actions.
