摘　　要：研究基于大量铁路路基连续压实和常规压实指标现场实测数据,结合室内土工试验和现场检测试验,运用一元线性回归分析了连续压实指标VCV值与常规压实指标压实系数K、地基系数K_(30)之间的相关关系,并考虑了含水率对相关程度的影响。同时,根据相关关系提出了一种快速判断现场路基填筑质量的评价方法及预测方法,并利用支持向量机回归算法和高斯噪声建立了检测指标的预测模型。In this study,based on a large number of railway roadbed compaction continuously and conventional compaction index field measured data,combined with the indoor geotechnical tests and field tests,using monadic linear regression analysis of the continuous compaction index VCV value with conventional compaction index compaction coefficient K,foundation coefficient correlation between K_(30),and considering the influence of moisture content of relevant degree.At the same time,according to the correlation,a method for evaluating and predicting the quality of subgrade filling is proposed,and the prediction model of detection index is established by using the regression algorithm of support vector machine and gaussian noise.
