摘要
为研究实际监测试验路段不同方案产生的压实度．基于实测路基填筑数据，运用灰色关联理论对不同要求压实度下的压实方案进行分析，取压实度在95％-98％的数据进行分析，找出压实度在此区间的最佳填筑碾压方案，以此指导路基填筑碾压，发现并不是碾压遍数越多越好，当土的干密度接近稳定时的碾压遍数即是所需的最佳碾压遍数。
Various test section for the study of actual monitoring scheme of compaction degree, based on the measured data of subgrade reclamation, using the grey relation to different requirements under the compaction degree of compaction scheme were analyzed, and take the compaction degree was 95% - 98% of the data analysis, find out the degree of compaction in the interval of the best filling rolling scheme, in order to guide roller compaction of subgrade reclamation. We found that it is not the more number of rolling times, the better, the rollinS times when the dry density of soil close to stability is the best what we need.
