Analysis of Anchor Load Tests for Stabilization of the Flying V Landslide: FHWA-WY-05/03F
Pre-design field load tests on ground anchors installed at an active landslide site are analyzed to provide information on anchor behavior. A total of six load tests were conducted with bond zones in three different geomaterials.
Test results are analyzed to determine bond capacity, load-deformation response, and constructability. These parameters are then applied to the design of a full-scale anchored slope stabilization system for the Flying V landslide. Both limit equilibrium and finite element analyses of the anchored system were conducted.
It is shown that the combination of pre-design load testing and FEM analysis can be used to investigate anchored slope behavior and design parameters more realistically than conventional limit equilibrium analyses, providing the opportunity to design more efficient and cost-effective stabilization systems.
