| 摘 要： | 为了检验玻璃纤维增强(GFRP)筋材是否可以作为岩土边坡钢筋锚杆的替代材料，采用布里渊光时域反射测量(BOTDR)技术检测GFRP锚杆的变形特征。试验研究结果表明，该方法是一种可行的手段，检测结果具有较高的可靠性；所用GFRP锚杆力学性状均一，性能稳定，具有良好的均匀受力性能，且具有很好的线弹性特征。

| Abstract: | In older to verify that the Glass Fiber Reinforced Plastic(GFRP) rebar can or not be used to replace steel rebar to reinforce soil slopes,the Brilliouin Optical Time-Domain Reflcetometer (BOTDR) is used to measure deformation characteristics of GFRP rebar. The results of test indicate this test method is feasible and effective, and the test results also have higher dependability.Through this measurement, it is found that the GFRP rebar adopted in this test has homogeneous and steady mechanical property, favorable and symmetrical stress performance ,and also good linear elastic characteristics. |
