Notes:
In this study, an experiment program is presented to study the bonding mechanismbetween corroded bolts and grout and in particular the influence on bonding behavior in terms ofdifferent corrosion sections along anchor. With respect to four groups of manufactured boltspecimens, the noncorroded and the corroded, respectively, on the front, middle and rear sectionalong anchor, a pullout test is conducted to reveal the relationship between load and loading-endslip and to investigate the bond-stress distribution characterization along full anchor. Experimentalresults show that corrosion product, acting as lubricating effect at the interface between bolts andgrout, can result in the degradation of bonding mechanical behavior. Meanwhile, corrosion ondifferent sections along anchor has a different effect on the anchorage capacity of bolts. Especially,corrosion on the front section induces the greatest decrease of anchorage capacity of bolts. Thus, itis concluded that the front section along anchor is the key region affecting the bonding mechanicalbehavior between bolts and grout
