This program will address the use of Direct-Anchorage installation methods for segmental retaining wall (SRW) applications. The presentation identifies site conditions that require innovative construction solutions to stabilize soil or rock conditions, and explains how tieback, soil nailing and anchorage system can be utilized. An overview comparing top-down construction techniques with traditional bottom-up methods for SRW applications is also reviewed.

Learning Objectives: 

  •  Participants will be able to describe applications that could benefit from direct-anchorage systems.
  •  Participants will understand the difference between top-down and bottom-up wall construction.
  •  Participants will be able to explain what geotechnical soil parameters are needed for direct-anchorage wall design.
  •  Participants will understand the general construction sequence related to direct-anchorage systems with SRWs. The process of actual wall installation from start to finish.
