| 摘 要： | 对预应力锚索最常见的破坏模式进行分析,着重研究由于预应力锚索几何形状引起的相互作用,采用解析方法分析锚索与砂浆界面的应力状态和破坏机理,得到的结果与现场观测及室内试验的破坏现象基本一致,并由此建立了极限承载能力计算公式。 |

| Abstract: | Commonly failure model of prestressed cable is analyzed. Much attention has been paid to geometric form of cable which influences bond strength. By means of theoretical method,the interface behavior between cable and grout is analyzed as well as its failure mechanism. Comparison with practical and laboratory test results has been made. It is shown that theory analysis is in good agreement with experimental results. Furthermore,the ultimate load carrying capacity is established. |
| Keywords: | rock and soil mechanics prestressed cable geometric form ultimate load carrying capacity |
