| 摘 要： | 为了解决分布式光纤在相似模型实验中的铺装方法以及光纤位置与被测模型的对应关系问题，提高测量结果的准确性，通过描述一个完整的分布式光纤测量相似模型变形的实验实例，给出了一种相似材料模型实验中分布式光纤的铺装方法，详细表述了铺装前光纤标记方法和整个铺装过程。给出了温度标记定位实验的详细步骤，并对定位实验结果及误差进行了详细分析，确定了光纤在模型中的实际位置，且定位误差不超过5 cm，定位精度较高。为采用分布式光纤测量模型实验内部变形的研究者提供了一种可借鉴的分布式光纤铺装、定位及分析方法。

| Abstract: | In order to solve the problem of pavement method of distributed fiber in similar model experiment and the correspondence between fiber position and measured model，improve the accuracy of measurement results.Through an experimental example，distributed fiber detection similar material simulation test deformation，a pavement method of distributed fiber in similar material simulation experiment is given，and the prefabricated fiber marking method and the whole pavement process are described in detail.The detailed steps of temperature marker positioning experiment are given，and the results of the experiment and the error are analyzed in detail.The actual position of the fiber in the model is determined，the positioning error is not more than 5 cm，and the positioning accuracy is higher.Which provides a kind of distributed fiber pavement，positioning and analysis method for researchers with distributed optical fiber measurement model internal deformation. |
