基于材料力学的基本原理，分析了结构监测过程中变形形态与应变之间的转换关系。利用分布式光纤测量系统测量结构表面应变的精确值，进而计算表面变形形态的强度。将光纤连接到柔性钢直尺表面，利用产生的应变数据精确测量了柔性钢直尺的端点变形形态。对计算的变形形态进行了计算，并与实际变形形态进行了比较。计算得到的变形构型曲线与实际变形构型曲线基本吻合（相对误差小于0.6%）。
In this study, the conversion relation between deformed configuration and strain during structural monitoring was analyzed based on the basic mechanics principle of materials. A distributed fiber optic measurement system was used to measure the accurate values of structural surface strain, and then calculate the intensity of surface-deformed configuration further. An optical fiber was attached to the surface of a flexible steel ruler, and the generated strain data were used to precisely measure the endpoint-deformed configuration of the ruler. Furthermore, the calculated deformed configuration was calculated and compared with the actual deformed configuration. It was found that the curves of calculated deformed configuration basically coincided (with a relative error of less than 0.6%) with the curves of actual deformed configuration.
