Mechanical Characterization of Anchor under Uniaxial Compression Loading Conditions

Bolt reinforcement technology plays an important role in supporting the construction of many engineering fields, and uniaxial loading characteristics behavior tests anchors have great significance to research application anchors. Therefore, four anchor specimens GA ∼ GD were fabricated tested explore macro microbehavior under compression. The stress-strain curves for GC compression analyzed. curve, elastic strain creep strain, failure results, electrochemical impedance spectroscopy specimen multistage investigated. results showed a series Under compression, shapes three similar, they had experienced different stages from stage I IV, respectively. After calculating compressive strength specimens, average these was σ c ¯ = 8.31 MPa. curve obtained by multi-stage test. total consisted strain. In whole process loading, proportion greater than that range 51.90% 55.82%. Seven spectrum load obtained. dispersion concentration Nyquist affected levels; higher level, more dispersed is. measured Bode diagram, compared with previous six measurements, variation laws value phase angle at seventh time quite different. above conclusions can provide some reference test theory
