Anti-floating anchor technology is widely used to resist the buoyancy generated by underground spaces,water supply,and building drainage structures.In anchor design,technicians pay too much attention to the pull-out bearing capacity and ignore the durability of anchors.After geological surveys of the site of a new water plant project in South China,it is found that groundwater has a general micro-corrosive effect on the steel bars in the concrete structure.To ensure the anchor's durability and reliability and meet the water plant's long-term use requirements,it is necessary to take corresponding anti-corrosion measures for anti-floating anchors.This paper conducts anchor pull-out tests under two conditions(without/with anti-corrosion coating).The test shows that the pull-out force of the anchor coated with anti-corrosion coating does not decrease significantly and meets the pull-out requirements.
