| Abstract: |
| In order to explore the deterioration law of bonding performance of anchor solid specimens after corrosion, the anchor structure of "concrete-bonding material-anchor" was taken as the research object. Considering the influence of joint number, joint position and bonding material on the mechanical properties of anchor solids, the accelerated corrosion of anchor solids was realized by electrification, and the load-slip curves of anchor solids were obtained through the pull-out test. The results show that: the more the number of joints in the specimen, the more the position is up, the more obvious the deterioration of mechanical properties after energized corrosion, the smaller the slope of the load-slip curve of the pullout test is, the greater the probability of occurrence of relative slip damage, and the deterioration of the mechanical properties of the anchors by the position of the joints is smaller than the number of joints. The effect of electrical corrosion on the deterioration of the mechanical properties of mortar anchor solids is more pronounced than that of resin anchor solids, which are less permeable. |
