Permanent Ground Anchors. Volume 2. Field Demonstration Project Summaries.

Page Count	322
Abstract	Ground anchors, often called tiebacks, are structural elements which receive their support in soil or rock and act to retain earth masses and/or applied structural loads. The Federal Highway Administration recognized that the use of permanent ground anchors in highway cut sections could affect substantial benefits in both economy and safety. The specific purpose of the permanent ground anchor demonstration project was to introduce the concept of permanent ground anchor use into American construction practice. A manual numbered FHWA-DP-68-1R and titled 'Permanent Ground Anchors' was prepared and several thousand copies distributed to highway engineers. Permanent ground anchors on several projects were monitored to validate the concepts addressed in FHWA-DP-68-1R. The report summarizes the results of both the field monitoring and the history of the permanent ground anchor demonstration project.
