摘要
预应力锚索因其安全简单,被广泛应用于锚固安全工程中。应力波反射法是广泛应用于锚固工程质量检测的一种无损检测方法,该文所设计的数据处理软件用来处理该方法所得到的数据。由于数据的时域特征不明显,该软件主要使用快速傅里叶变换及谱能比法在频域上进行处理,以求得锚索的自由段长度。该文介绍了锚索检测的基本方法后,叙述了软件设计的框架、流程及结果,在实际应用中取得了较好的效果。
Prestressed Anchor Cable, for its safety and simplicity, is widely used in rock and earth anchoring constrcution. Stress wave reflection method is widely used to detect anchoring constrcution quality as a non-destructive method. The data processing software refered in this paper is designed for processing the data obtained by this method. As the time-domain characteristics of the data is not obvious, the sott＇ware mainly uses the Fast Fourier Transform and the Spectrum-Energy ratio processing data in the frequency domain to achieve the free length of the anchor. This paper introduces the basic method of the anchor cable detection and the framework, the process and the result of the software design. And does well in practical applications.
