%X 碳纤维复合材料(CFRP)片材具有质量轻，高强度特性，在预应力碳纤维板加固技术中，锚夹具的可靠性是该技术成败的关键。通过实验来探究螺栓预紧力的损失量与不同初始预紧力的关系，用Origin软件进行分析，并拟合出螺栓预紧力与时间的幂函数关系式，为波形锚具在实际工程中的应用和对锚具的性能优化提供合理的数据。<br />
CFRP sheet has the characteristics of light weight and high strength. In the prestressed CFRP strengthening technology, the reliability of anchor fixture is the key to the success or failure of the technical performance. Through experiments, the relationship between the loss of bolt preload and different initial preloads is explored and analyzed with Origin software, and the power function relationship between bolt preload and time is fitted, which provides reasonable data for the application of waveform anchorage in practical engineering and the performance optimization of anchorage.
