摘要
对某国一段未修建完成的铁路路基的质量进行检测、评估,以判断路基能否继续使用。研究现有的路基检测技术,综合采用了地质钻探取样填料土性试验法、物探法等检测方法,对路基质量进行综合评价,完成了既定的检测目标,达到了预期检测效果。
The unfinished existing railway subgrade in a country was tested and evaluated in order to judge whether the subgrade can be used continuously. The existing subgrade detection technology was researched with comprehensive detection methods of geological drilling sampling filling soil test method, and geophysical method, subgrade quality has been comprehensively evaluated which makes established detection target complete and good detection effect achieve.
