Deformation is a ubiquitous phenomenon in nature. This process usually refers to the change in shape, size, and position of an object in the time and spatial domain under various loads. Under normal circumstances, during engineering construction, technicians are generally required to monitor the safe operation of structural facilities in the transportation field and the health of bridge, because monitoring in the engineering process plays an important role in construction safety. Considering the reliability risk of sensors after a long-time work period, such as signal drift, accurate measurement of strain gauges is inseparable from the value traceability system of high-precision strain gauges. In this study, two vibrating wire strain gauges with the same working principle were measured using the parallel method at similar positions. First, based on the principle of time series, the experiment used high-frequency dynamic acquisition to measure the thermometer strain of two vibrating wire strain gauges. Second, this experiment analyzed the correlation between strain and temperature measured separately. Under the condition of different prestress, this experiment studied the influencing relationship of temperature corresponding variable. In this experiment, the measurement repetitiveness was analyzed using the meteorology knowledge of single sensor data, focused on researching the influence of temperature and prestress effect on sensors by analyzing differences of their measurement results in a specified situation. Then, the reliability and stability of dynamic vibrating wire strain gauge were verified in the experiment. The final conclusion of the experiment is the actual engineering in the later stage. Onsite online meteorology in the application provides support.

基于振动线应变传感器的桥梁并联结构温度和应变相关性。

变形是自然界普遍存在的现象。此过程通常是指在各种负载下，对象在时间和空间域中的形状，大小和位置的变化。通常情况下，在工程建设过程中，通常要求技术人员对交通运输领域的结构设施的安全运行和桥梁的健康状况进行监控，因为在工程过程中进行监控对于建筑安全至关重要。考虑到长时间工作后传感器的可靠性风险，例如信号漂移，应变仪的准确测量与高精度应变仪的价值溯源系统密不可分。在这项研究中，使用平行方法在相似位置测量了两个工作原理相同的振弦式应变仪。第一，根据时间序列原理，实验采用高频动态采集法测量了两个振弦式应变片的温度计应变。其次，该实验分析了应变和温度之间的相关性。在不同的预应力条件下，本实验研究了温度对应变量的影响关系。在本实验中，利用单传感器数据的气象知识分析了测量的重复性，重点是通过分析特定条件下测量结果的差异来研究温度和预应力效应对传感器的影响。然后，通过实验验证了动态振弦式应变仪的可靠性和稳定性。实验的最后结论是后期的实际工程。现场在线气象在应用程序中提供了支持。
