摘要
对螺纹状和光面两种不同表面特性的GFP-SN进行了室内拉拔试验,以砂浆为锚固体,研究了室内拉拔试验中GFP-SN承受拉拔荷载的力学特性。结果表明,GFP-SN的表面特性对其拉拔性能和破坏形式影响较明显,在破坏前GFP-SN的各点应力随拉拔力增大而增大,GFP-SN的埋设范围内应力大小分布不均匀。
Based on indoor drawing test with thread GFP-SN and smooth surface GFP-SN, the mechanical characteristics of GFP-SN under drawing load are analyzed by taking mortar as the anchor body. The results show that the drawing performance and failure modes of GFP-SN are affected obviously by its surface characteristics; the stress of GFP-SN in- the stress distribution of GFP-SN is non-uniform within the embedded range.
