• Abstract:
  Research directed toward improving the design and construction of permanent ground anchor walls is presented. The research focused on tiedback soldier beam walls for highway applications. These walls are generally less than 25 ft high, and they are supported by one or two rows of permanent ground anchors. This volume is part of a four-volume report summarizing the research. It presents apparent earth pressure methods for determining the lateral earth load. Differences between anchored and braced walls are discussed. The limiting equilibrium bases for the apparent earth pressure diagrams are reviewed. Current force equilibrium methods {simple limiting equilibrium methods) for evaluating the external stability of an anchored wall are reviewed. A force equilibrium method is developed and used to illustrate how anchor position, soil strength and the location of the failure surface affect anchor load, and internal and external stability of a wall. The factor of safety inherent in the apparent earth pressure diagram is determined. Recommendations for using general purpose slope stability computer programs for determining lateral load and evaluating internal and external stability of an anchored wall are made. This volume is the first in a series. The other three volumes are entitled: FHWA-RD-98-066 Volume II Full-scale Wall Tests and a Soil-structure Interaction Model FHW A-RD-98-067 Volume III Model-scale Wall Tests and Ground Anchor Tests FHWA-RD-98-068 Volume IV Conclusions and Recommendations In addition, a manual and computer program were developed that incorporate research results. They are entitled: FHWA-RD-97-130 Design Manual for Permanent Ground Anchor Walls FHW A-RD-98-093 TB Wall - Anchored Wall Design and Analysis Program for Personal Computers.
