摘　　要：路基是公路的重要组成部分,是路面的基础。因此,它的质量好坏,直接关系到整个公路。通过数理统计中的直方图、χ2拟合检验法检验判断过程的数据是否服从正态分布,然后在此基础上用质量控制图来判别路基施工过程中质量是否稳定。通过对数据的及时检测和分析,可以及时发现路基施工过程中的质量问题,以便施工单位及时采取补救措施。The embankment is not only an important part of the highway,but also the basis of the road,so the quality of it,is directly related to the entire road. In this paper, using the histogram of mathematical statistics,x^2 test to determine whether it is in the course of normal distribution,and then on the basis of quality control chart used to determine the quality of the construction process embankment is in the stability. The timeliness of data through testing and analysis,can be found quality issues of embankment construction, and make construction units to take timely remedial measures.
