Four groups pull-out model tests of underreamed ground anchor were done by self-designed anchor drawing device,which was used to research the ultimate bearing capacity about diameter and length of underreamed segment.The test results show that Q-s curves have three phases,expanded diameter has more impact on the ultimate bearing capacity,and the effect of length is relatively small.The underreamed anchor has obviously the size effect,the optimization of underreamed bodys diameter and length will achieve the technical advantage and economical benefit in practice.
