Other Abstract 冲击碾压法具有施工快速、造价经济等特点,已在国内外公路、铁路、机场及港口等工程中得到广泛应用.采用室内击实试验模拟冲击碾压过程中的冲击作用,通过对击实后的粉土试样进行压缩试验和直剪试验,从土的压缩变形和抗剪强度变化的角度,研究了土中含水率对粉土冲击压实效果的影响.结果表明,粉土的最优含水率在23%~24%范围内;粉土在低于最优含水率情况下的冲击压实效果好于在高于最优含水率情况下的冲击压实效果. 
;  The impact roller(IR)compaction method,widely used in engineering of highway,railway,airport and port at home and abroad,has the advantages of high efficiency of construction and cost saving. Compaction test was used to simulate the impact process of IR compaction. Compression tests and direction shear tests were carried out on the silt samples adopted from silt after the compaction to investigate the influence of water content on the effect of silt subjected to IR compaction. The results show that the optimal water content of silt ranges from23% to 24% and the improvement effect of silt with lower water content than optimal water content is better than that of silt with higher water content than optimal water content.
