玻璃纤维筋抗浮锚杆在某工程中的抗拔试验研究与应用

Research and Application of Anti-floating Anchor with Glass Fiber Reinforced Polymer in Pull-out Test of a Certain Project

抗浮锚杆是建筑工程地下结构抗浮措施的一种,在地下工程中广泛应用,常用杆体材料为钢筋,但玻璃纤维筋(GFRP)抗浮锚杆的研究与应用较少。通过在某工程的应用,并对玻璃纤维筋与传统材料抗浮锚杆进行抗拔对比试验,采用极限抗拔试验验证了玻璃纤维筋作为抗浮锚杆的可行性,为玻璃纤维筋(GFRP)在地下工程应用提供设计、施工依据。

Anti-floating anchor rod is a type of anti-floating measure for underground structures in construction engineering,widely used in underground engineering.The commonly used rod material is steel bar,but there is relatively little research and application of glass fiber reinforced polymer(GFRP)anti floating anchor.Through the application in a certain project,a comparative test was conducted on the pull-out resistance of glass fiber reinforcement and traditional material anti-floating anchors.The feasibility of using glass fiber reinforced polymer as an anti-floating anchor was verified through ultimate pull-out test,providing design and construction basis for the application of glass fiber reinforced polymer(GFRP)in underground engineering.
