摘  要:
采用有限元法对锚索和锚固体和软钢在准静态受力过程进行了数值计算,分析了一种软钢防护装置对锚固体的防护作用。分析过程中不仅考虑了软钢的变形,而且还考虑了锚索的自身变形。通过锚索和软钢吸能,改变了锚固段的应力分布和轴力分布,防止了岩体的破坏。研究结果表明,所采用的耗能装置能有效缓冲由于地震和其他外荷载所产生的冲击,防止锚固结构在一定冲击下的破坏。

摘  要:
Finite element method was applied to do the numerical calculation of anchor cable, anchoring and mild steel in the quasistatic stress, and analyze the protective effect of a mild steel protection sets for the anchoring. In addition to deformation of mild steel, deformation of anchor cable was also considered. Energy-absorbing anchor cable and mild steel changed the stress distribution and axial force distribution of anchoring section, so damage of rock mass was prevented. The results showed that the applied energy-consuming sets could buffer the shock of earthquake and other external loads, and prevent damage of anchoring structure.
