以2种不同的细粒土及18种不同级配的含粗粒的细粒土为研究对象,进行了大量的室内击实试验,来寻求含粗粒的细粒土的最佳击实功,从而确定当路基填料为含粗粒的细粒土时,其室内最大干密度的试验方法.在此基础上,提出含粗粒的细粒土的最大干密度宜采用重型击实试验法确定,且每层的击实次数宜增加为130击.同时,利用多元线性回归方法对试验结果进行了分析,得到了最大干密度与土中各个粒组含量之间的线性关系式.结果表明,含粗粒的细粒土的最大干密度与各粒组含量之间存在良好的线性关系.

Through compaction test of 2 kinds of fine-grained soil and 18 kinds of soil containing coarse granulae in the lab,the optimum compaction energy of the soil containing coarse granulae is studied when it is used as the embankment fill material.The test results show that the suitable test method of the maximum dry density for the soil containing coarse granulae is heavy compaction test; and the compaction times should be increased to 130 for each layer.The relationship between the maximum dry density and the granulae size group is analyzed through multiple linear regression; and the results show there is a good linear relationship between them.
