MATLAB超长光纤光栅沉降管挠度计算算法研究

摘要随着科技水平的不断提高，光纤监测技术逐渐被人们所重视。相比于其他的监测手段，光纤监测有着不可比拟的优势。但是由于监测技术和数据处理技术的落后，这种监测手段难以得到推广。本文详细介绍了光纤光栅传感技术的发展、工作原理以及工程应用。针对武汉二环线改造工程，以超长光纤光栅沉降管测量技术为基础，通过编写MATLAB程序，利用这一软件完成超长光纤光栅挠度计算的算法研究，并在实际应用中证明了其实用性。论文中将对超长光纤光栅沉降管的工作原理和研究成果以及MATLAB这一软件的应用做具体的介绍。同时提出有关于本算法的其他想法，指明了今后相似算法的研究方向。10024

Title      Study on the algorithm of the Long distributed
optical fiber grating settlement tube deflection calculation
Abstract
With the continuous improvement of science and technology, people have been paid more attention to optical monitoring techniques gradually. Compared with other means of monitoring, the advantages of optical fiber monitoring are unparalleled. However, because the monitoring and data processing technology is backward, this technology is difficult to popularize. This article illustrates the development of the distributed optical fiber sensing technology in the world, its working principle and engineering applications.With Long distributed optical fiber grating settlement tube technology as the foundation, I completed the algorithm of the Long distributed optical fiber grating settlement tube deflection calculation through MATLAB software and in the actual application we have proved its practicability.In this paper,I will introduce the Working principle of the FBG settlement tube, it’s research achievements and the application of the MATLAB software in this algorithm.At the same time,I will put forward some other ideas about the algorithm which was got in the process of research,and point out the future study direction of the similar algorithm.
Keywords: Long distributed optical fiber grating settlement tube

1.1 选题背景与现状
我国人均资源相对贫乏，石油、天然气、可耕地和水资源人均拥有量仅为世界人均值的1/9、1/23、1/3和1/4。我们要保障13亿人口大国的粮食安全，没有足够的土地支撑是断然不行的；要建成全面小康社会、富裕发达国家，实现工业和交通现代化，搞城市建设提高城市化水平，没有足够的土地、能源、水资源的支撑同样也是断然不行的。 MATLAB超长光纤光栅沉降管挠度计算算法研究:http://www.youerw.com/gongcheng/lunwen_8931.html
