The invention belongs to the technical field of geotechnical engineering stress analysis, and relates to a method for analyzing axial force and displacement distribution of an overall-length bonded GFRP anti-floating anchor rod. An anchor rod body and an anchoring body are regarded as a whole, a linear elastic theory analysis method is adopted, the stress condition of the anchor rod body is independently analyzed, and therefore the slippage and destroying phenomenon of the anchor rod body in the actual situation is explained; different from a non-overall-length bonded anti-floating anchor rod,the mechanical and displacement performance of the overall-length bonded GFRP anti-floating anchor rod is described from the microscomic point; and compared with actually measured experiment data, correction is carried out, the precision of a set-up function model is high, and a theoretical basis is provided for further microscomic study of the stress rule of the overall-length bonded GFRP anti-floating anchor rod at different depths.
