摘要
在分析传统锚杆监测系统的缺点和光纤光栅传感技术的优点的基础上,通过对全长锚固锚杆的受力分析,设计了一套新的光纤光栅锚杆监测系统.采用相似材料模拟试验手段,对全长锚固锚杆做了拉拔实验及分析,验证了光纤光栅锚杆监测系统的可行性.
The FBG anchor monitoring system is discussed based on the analysis of the shortcomings of traditional anchor monitoring system and the virtues of FBG technology, through to span anchor rod stress analysis, a set of new fiber grating anchor rod observation system is designed. The paper educes the feasibility of FBG anchor monitoring system through the analysis of the pull experiment of the full grouting bolt.
