Abstract

Anchorage diameter and interface characteristics of soil-anchorage body are critical factors to affect the ultimate bearing capacity of anti-floating anchor.The rotary jet grouting anchors are constructed and the cycle loading pullout tests of anchors are conducted in the layer of soft rock.The test results show that anchors’failure mode has the process of rebar yielded first,then pulled out and anchorage body drawing breakage.The ultimate bearing capacity value of anchors is more than 900k N,which can meet the requirment of practical engineering.
