Abstract	Because of the chemical corrosion of underground water on rock bolts that persistently present in complicated geological conditions, the mechanical properties and integrity of bolts may be affected, even bolt failure may occur. In the present article, first, the effect of the chemical reaction and the corrosion expansion on bond strength has been analyzed. Second, a coupled creep model of anchor structures and soil has been proposed based on the stress condition and deformation characteristics of the anchor segment. In this model, the Mohr–Coulomb (M–C) plastic element was used to simulate the complete creep deformation, and the constitutive equation of the coupled creep and the loss of the anchor force were obtained. A comparison between previous studies and the present model indicates that the results of this model agree well with previous results. The coupled creep of the anchor segment and soil is properly reflected in this model. Thus, this model can accurately predict the variation of the anchorage force.
