摘　　要：介绍了无核密度仪的检测原理,论述了核子密度仪测试结果同现场取芯结果的对应性,并讨论了温度与压实度随碾压遍数的变化规律。The measuring principal of non-nuclear density gauge was discussed. The measuring error of different types of gradations as Superpavel2.5, Superpavel9 and AC-16 was investigated compared with non-nuclear density gauge measure result and coring measure result. The changing of temperature and density during construction was also discussed in this paper.
