摘要
低应变时域分析中包括几种信号放大技术,分别是"指数放大"技术、"线性放大技术"及"扫描式局部线性放大"技术。通过介绍各种放大技术特点,并进行对比与评估,举实例进行分析,得出"扫描式局部线性放大"技术具有明显的适用性和优越性的结论,其宜在基础工程质量检测中推广。
Low strain time domain analysis include several signal amplification techniques, including index multiplication, linear amplification and scan type local linear amplification, etc. This paper introduced the characteristics of different amplification techniques, which were then compared and evaluated. After analysis on practical cases, it was shown that the scan best and the most applicable, so it should be promoted type local linear amplification technique was the in quality inspection of foundation project.
