    • Abstract
  • Based on the description of the developing history, the bearing capacity and failure mode of under-reamed ground anchor, the advantages of its bearing capacity and the rationalities of its failure mode are elaborated compared with those of normal tension-type anchor. According to the advantages of under-reamed anchor, a capsule-type under-reamed anchor with multiple anti-corrosion function is developed. Besides, structure, its construction technology, construction equipment and the applicable soil conditions are all discussed. Finally, combined with some classic applications of the capsule-type under-reamed anchor with multiple anti-corrosion function, the current situation of its promotion and application in China is introduced.
