Title:

New Application of Low Strain Impact Integrity Testing in Highway Guard Rail Post Embedding Depth Measurement

Accession Number:

01334281

Record Type:

Component

Abstract:

The primary goal of this study is to develop a fast and reliable alternative testing method, low strain impact integrity testing based measurement technology to test hallow piles embedding depth. A number of innovative techniques are developed to solve the problem, such as automated agitation, free vibration elimination software, reflection wave extraction, enhancement and analysis method, high-precision spectral analysis, an intelligent post length evaluation system, and so on. This new technology has been successfully verified in multiple highway construction projects in China.
