| 摘 要： | 以兰新铁路第二双线路基试验段戈壁填料现场填筑试验为依据，分析了路基压实指标K30与Ev2的区别与联系；总结了4个试验工点K30与Ev2及Ev1变形曲线特性，并对地基系数K30与变形模量Ev的相关性进行了分析。结合室内土工试验，对影响K30与Ev2的因素进行总结。结果表明：填土的密实程度是影响K30与Ev1及Ev2/Ev1的主要因素；填料的性质是影响Ev2的主要因素，对 Ev2/Ev1也有较大影响；Ev2为填料的特征参数，反映了路基的刚度；K30为填土压实质量控制指标，K30与Ev1的相关性较好，与Ev2的相关性相对较差，K30与Ev1及与Ev2的相关性的好坏还与填料的性质有关，检测指标越离散，相关性越差
