无核密度仪在路基压实度中的应用研究

Application of Non Nuclear Density Gauge in the Roadbed Compaction Degree

通过灌砂法对砂垫层压实度的检测以及环刀法对路基的压实度检测,对比无核密度仪的检测结果。研究结果表明,无核密度仪的检测结果与环刀法的检测结果比较接近,并根据计算得到了换算系数,为实际工程检测提供了理论参考。

Through the sand filling method to detect the compaction of sand cushion and the cutting ring on the roadbed compaction degree,The detectionresultsof non nuclear density.The results show that,compared to the results of detection results of non nuclear density gauge and cutting ring method,and according to the calculation and get the conversion coefficient,provides the theory reference for the practical engineering testing.
