膨胀土高边坡FRP类锚杆支护对比研究

Comparative study on FRP anchor support of expansive soil high slope

膨胀土边坡在膨胀土地区经常出现,考虑采用纤维增强聚合物锚杆作为支护,即研究FRP类材料锚杆替代钢材锚杆。并制定CFRP锚杆和GFRP锚杆对比试验方案,将两类锚杆的应力、位移、极限承载力等试验结果对比分析,得出两类锚杆在三个方面的性能与效果,最终得到了有益结论。

Expansive soil slopes often appear in expansive soil areas. Fiber reinforced polymer anchor rod is considered as support. Research on FRP anchor rod replacing steel anchor rod. Develop a comparative test plan for CFRP anchor rods and GFRP anchor rods. The test results of stress,displacement and ultimate bearing capacity of the two types of anchor rods are compared and analyzed. The performances and effects of the two types of anchor rods in three aspects are obtained. The beneficial conclusion has been drawn.
