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

摘要

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 embeddingdepth. A number of innovative techniques are developed to solve the problem, such as automatedagitation, free vibration elimination software, reflection wave extraction, enhancement and analysismethod, 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 inChina.
