Numerical Investigation of the Performance of a New Anchored Micropile Structure Against Landslides

As a remedial measure against slope failure, an anchored micropile structure (AMS) was proposed comprising a conventional micropile structure (CMS) and anchor tieback. Numerical investigations of performance of the AMS and CMS were performed. Improvement was observed in the displacement field of slope reinforced by AMS. The rotation deformation of CMS is replaced by flexure deformation in AMS. Displacement of AMS is less than CMS. The tieback acts in both deformation control and stress optimization. The reduction in extreme value of bending moment is equal to 35%. At axial force, the sharing ratio was decreased from 2.43:1 to 1.25:1.
