| 摘 要： | 水对树脂锚索锚固性能具有影响,可导致锚索锚固失效。通过室内树脂锚固锚索拉拔试验以及长锚索锚固试验,系统研究了水对树脂锚索锚固性能的影响,得出水可降低锚固粘结强度约7%,降低锚固体单轴抗压强度约12%,减少有效锚固长度约10%。研究结果对定量评价巷道锚索支护的安全性以及合理设计树脂锚索的支护参数具有重要意义。

| Abstract: | The water has an effect on anchoring performance of resin cable bolts. In some case, water could lead to the failure of cable bolts reinforcement. Based on the cable bolts pull-out tests and long cable bolts installation tests in laboratory, the anchoring capability is studied systematically. The research result shows that water can reduce the cable bond strength about 7 %, reduce the anchoring body uniaxial compression strength about 12 %, and shorten the effective anchoring length about 10 %. The achievement is valuable to the design of roadways cable bolts supporting parameters and the evaluation of reinforced rock masses’ safety. |
