摘要
压实度作为评价道路路基施工质量的重要指标之一,其检测方法是影响该指标的重要因素,采用4种不同压实度检测方法对试验路段路基进行平行检测,以灌砂法作为标准测定方法,按最小二乘法对检测结果进行回归,建立相关函数,分析其相关性和差异性,通过分析得出:核子密度仪法检测结果相关系数大于0.9,可以作为工程质量评定与验收依据;灌砂法与核子密度仪法配合使用,既可以提高检测的效率,又能够对检测结果随时进行比较,提高检测质量与精度,为路基压实度快速测定提供参考。
One of the important indicators for evaluating the degree of compaction of road subgrade construction quality,the detection method is an important factor affecting the index,the paper mainly uses four kinds of different detection methods to test the degree of compaction road subgrade parallel detection,with sand filling method as a standard measurement method,according to the least squares regression method on the test results,establish related functions,analyze the relevance and difference,the conclusions are as follows： test results nuclear density instrument correlation coefficients greater than0. 9,can be used as basis for engineering quality assessment and acceptance; sand replacement method used in conjunction with the nuclear density gauge method can not only improve the efficiency of detection,but also to compare the test results at any time,to improve the quality and accuracy of detection and provide reference for rapid determination of subgrade compaction.
