| 摘 要： | 介绍了一种新型的土钉抗拔试验装置,对抗拔试验箱的设计、传感器布置以及实验步骤等进行了详细地阐述.试验主要研究了上覆土压力、土样饱和度和灌浆压力对土钉抗拔性能及抗拔强度的影响.试验结果表明钻孔灌注型土钉的抗拔强度与上覆土压力基本无关;随着土样饱和度的增加,土钉的抗拔强度呈先增加后减小的模式;土钉抗拔强度受灌浆压力影响很大,随灌浆压力的增加而显著增大. |
| 关 键 词： | 土钉 抗拔强度 完全风化花岗岩 |

| Abstract: | An innovative laboratory pull-out box is introduced in this paper.The design of the pull-out box,instrumentations and test procedures are described in detail.Parameters that influence the pull-out behavior and pull-out resistance of soil nails such as overburden pressure,soil degree of saturation and grouting pressure were investigated in the tests.Test results showed that the pull-out resistance of a soil nail was not directly related to the overburden soil pressure.With the increase in soil degree of satu... |
