摘　　要：用常温高浓度加速老化的方法分别做了普通环境和酸碱腐蚀环境条件下GFRP锚杆力学性能的试验,对比分析其被腐蚀后外观颜色、尺寸等的变化及其抗拉强度、抗剪强度、弹性模量等力学性质指标的损失量,研究其被介质腐蚀前后是否存在着显著差异,试验证明,GFRP锚杆具有较强的耐酸碱性能,具有很高的推广应用价值和广阔的发展前景。The GFRP anchor arm mechanics properties under common environment and acid-base environment situation were tested with normal temperature accelerated aging method,the external appearance color,size change after corrosion and loss of its tensile strength,shear strength,elastic modulus etc. mechanics properties index were compared and analyzed,whether it had marked differences before and after corrosion by material or not was studied.The test indicated that GFRP anchor arm had strong acid-base resistance,which had very high popularization value and bread development foreground.
