New system for investigating the corrosion of existing rock anchors

[摘要] In this study, the characteristics of corrosion were described on the basis of previous findings on the corrosion of rock anchors, and various factors causing corrosion were explored. A corrosion investigation system of rock anchors was established by summarizing various methods for the detection of corrosion and influencing factors. In this system, corrosion was investigated by detecting and assessing the environmental influencing factors, analyzing the corrosion rate and morphological characteristics, testing the anchoring structure, and evaluating the causes, development, and prediction of corrosion. On-site corrosion cases were also examined. Results verified that this system is reasonable, effective, and practical.
