Case History – Hollow Bar Micropiles for Settlement Control

Hollow bar micropiles exhibit outstanding bond transfer values and have the ability to reinforce soft/loose soils thus improving the settlement behavior of foundations utilizing them. The behavior of hollow bar (fully bonded) micropiles in soil will be examined and a case history discussed where over 1000 hollow bar micropiles were used to reinforce soils beneath heavily loaded equipment pads at an aircraft manufacturing facility in soft coastal plain soils. A model of bonded anchors / micropiles in soil is developed for characterizing and describing micropile behavior. An extensive load testing program was implemented to optimize micropile lengths and finite element modeling was utilized to quantify the amount of improvement achieved by the micropiles.
