CFRP ground anchors have an integral place in the ground anchor industry, providing designer and contractors with a corrosion resilient anchor which minimises the labour intensive corrosion protection required when using steel strands. Successful anchoring of long strand lengths in a confined ground anchor environment has been the greatest constraint in the development of CFRP ground anchors. Recent research undertaken at Monash University and Geotechnical Engineering has developed a reliable and compact bond type anchorage head system, practical for permanent ground anchor applications. Laboratory and full scale testing has been successfully carried out. This paper provides tests results on a four and ten strand CFRP modified bond type anchor head system with a reduced bond length. Results showed failure of specimens were within the CFRP fibres due to tensile rupture. Negligible movement at the bond anchor head were recorded.
