中文摘要：

土遗址锚杆锚固质量一直是土遗址加固工程中关注的重点问题。目前，土遗址领域均采用具有破坏性的拉拔试验对其进行检测。基于土遗址的文物属性，本研究尝试利用无损检测技术评价土遗址加l虱用玻璃纤维锚杆的锚固质量。通过锚杆无损检测仪与拉拔仪分别对甘肃省红沙堡遗址与永泰城址加固工程中的玻璃纤维锚杆锚固系统进行检测。比较实际测量杆长与仪器测量杆长结果，得出杆长指标可以判断无损检测仪所测结果的真实性。无损检测仪得出的检测波形衰减规律显著，对比相应锚杆的拉拔试验的评价结果，证实了声频应力波法在土遗址玻璃纤维锚杆锚固系统无损检测中的适用性。本研究结果将为评价土遗址加固用玻璃纤维锚杆锚固质量提供可靠的依据。

英文摘要：

The reinforcement of earthen sites always focuses on quality of the anchor system. Currently, pull - out testing is the only way to test earthen site anchor systems. This research used nondestructive testing technology for the first time to evaluate glass fiber reinforced polymer （GFRP） anchor system in earthen sites. In the Hongshabao and Yongtaisites, in Gansu Province, GFRP anchor system in earthen sites was tested by using a nondestructive an- chortesting instrument and a pull - out apparatus. By comparing the actual measuring bolt length and instrument measuring bolt length, it is found that the length index is good at judging the validity of results measured using the nondestructive detector. In comparison with bolt pull - out testing results, it is confirmed that the nondestructive method for testing GFRP anchor system in earthen sites is suitable and accurate. The results of nondestructive tes- ting of GFRP anchor system of earth sites is proved to be accurate.
