摘要

对于高液限土（包括改良的高液限土）填筑的路堤只用单一的压实度指标控制常常易导致质量隐患。通过试验研究提出一个采用空气率Va和压实度Dc双指标控制高液限土路堤填筑质量的方法，并给出了具体的控制标准。当压实度控制指标Dc≥93%时，高液限黏土和粉土空气率控制标准为4%≤Va≤8%，含砂高液限黏土和粉土空气率控制标准为6%≤Va≤13%。通过系统的试验研究，验证了双指标质量控制的可行性和有效性。研究结果表明，采用空气率和压实度双指标控制，不仅可以保证高液限土填筑路堤的强度和刚度，而且具有较好的水稳定性，为进一步充分利用高液限土作为路堤填料提供了技术支持。

Abstract

Great amount of engineering practices indicate that the single index Dc

degree of compaction could not well control the quality of embankment filled with high liquid limit soil (including the improved high liquid limit soil)

and may cause quality hidden dangers. Through experimental study

this paper proposes a quality control method using two indices to control the quality of embankment filled with high liquid limit soil; and the two indices are the volume ratio of air Va and the degree of compaction Dc. When Dc is more than 93%

the suggested value for high liquid limit soil (or silt) is 4%≤Va≤8%

and the suggested value for high liquid limit sand soil (or silt) is 6%≤Va≤13%. The feasibility and validity of this two indices quality control method was verified through tests in laboratory and test sections. The results show that adopting the two indices (Va and Dc ) could not only guarantee the intensity and stiffness

but also ensure better water stability

so as to provide technical supports for further full use the high liquid limit soil as embankment filler.
