Abstract: A construction process for partially bonded prestressed uplift-resistant glass fiber anchor piles avoiding stress concentration includes the following steps: construction site management, determining anchor pile locations, drilling a borehole using a spiral drilling rig, lowering a pre-fabricated glass fiber rod cage into the borehole after inspection, performing grouting, making adjustments, and repeating the above operations. The construction process adopts a layout that avoids stress concentration, demonstrating its superiority in strata with developed horizontal bedding. Simultaneously, it uses glass fiber material with good corrosion resistance, meeting the requirements for uplift-resistant anchors under corrosive conditions. It employs a partially bonded prestressed design, changing the mechanical characteristic of traditional uplift-resistant anchors from becoming looser when pulled to a wedge-like characteristic of becoming tighter when pulled.
