【摘要】 通过改变室内击实试验的击实参数,对影响粗粒土压实特性的相关因素进行分析;利用现场试验,对粗粒土路基压实厚度、压实机械及压实遍数等影响压实效果因素综合分析后,针对粗粒土中粗粒含量的变化,提出采用三点二次插值函数的定量分析方法及定量与定性分析相结合的方法对粗粒土的压实质量进行评价。结果表明,含水量对粗粒土压实影响较小,应采用大吨位的振动压路机对粗粒土进行压实。更多还原

【Abstract】 In the experiment, the compaction parameters were changed to test the compaction results, so as to reveal the factors, which influence the compaction results. The compaction depth, compaction mechanics and compaction times were surveyed, the surveying data were analyzed with three-point two-time interpolation function to develop a evaluating system for coarse-grained soil. The results show that the moisture content has little influence on the compaction of coarse-grained soil, so the heavy vibrating compactor should be adopted to compact coarse grained soil.更多还原
