Document Type: Journal Paper


The current philosophy and practice of Bechtel Incorporated in the treatment of abutments and foundations of high embankment dams on rock are considered, with special reference made to the recently completed New Don Pedro Dam in California. The influences of site geology and topography on dam design, including grouting, stripping, rock reinforcement, and determination of acceptable rock foundation surface are considered. Foundation beneficiation such as the use of dental concrete and installation of French drains and relief wells and instrumentation such as piezometers at New Don Pedro and other dams are used to illustrate the steps taken to ensure satisfactory foundations for high embankments on rock foundations.
