Stress Loss Analysis of a Geotechnical Prestressed Anchor under a Corrosive Environment in a Coastal Area

The corrosion of geotechnical prestressed anchor rods directly affects the safety structure engineering. To this end, an experimental device for measuring stress loss was developed, which used to study a under corrosive environment, obtain change curve structure, and analyze influence environment on in coastal areas. final results show that degree damage bolts determined by cross effect stress, most occurred early stage after loading. resulted mainly from bond degradation section, partly elastic modulus rod body. Corrosion reduced bonding force bolt strength bolt–grouting body, body greater than strength. maximum axial rock–soil 11.6%. When oxygen concentration higher, rate greater. Therefore, accelerated indirectly increases bolts.
