摘要
采用灌砂法、环刀法、核子密度仪法、落锤频谱式快速测定仪(LY-I仪)法4种方法对检测路基压实度的测试结果进行了比较分析;并以灌砂法作为现场测定压实度的标准方法,将其他方法与灌砂法进行回归标定,得出了相关关系,进一步证实了采用灌砂法作为路基压实度检测的标准方法是值得推广的。
The paper determines compaction degree of subgrade making use of pumped sand, cutting ring, nuclear density instrument and drop hammer frequent mensuration methods. And compares the detection result of four methods, then take sand cone method as standard one, regress these methods and sand cone method. Consequently approves pumped sand method which is the standard one is worthwhile promoting.
