| 摘 要： | 现行公路规范以现场实测压实度K值来评定路基填土的压实质量。结合压实度的检测，在现场同时进行地基系数K30的测试，比较结果表明以地基系数如与压实度K综合评定公路路基填土压实质量是可行的，并确定评定公路路基填土压实质量的‰指标值，推导出变形模量Ev与地基系数K30的关系式，从而得出评定路基填土压实质量的变形模量指标．有助于公路路基填土压实度的质量评定。

| Abstract: | Measured K value of compactness is used to evaluate subgrade filled soil compaction in the current highway norm. Besides, base coefficient K30 is measured. The comparison shows that it is feasible that the two indexes are combined to evaluate the compaction quality. What＇s more, K30 index is determined and the relational expression between deformation modulus Ev and base coefficient K30, thus deducing the deformation modulus index to evaluate subgrade filled soil compaction quality. It is helpful for quality evaluation of highway subgrade filled soil compaction. |
