摘要： 以三亚地区珊瑚礁砾石土为路基填筑材料，采用室内试验手段，开展现场均匀级配下钙质砂及礁岩碎屑物（含砾块）混合料的击实试验，分析击实层数和击实功对填料压实效果的影响，对珊瑚礁碎屑沉积物的路用潜能作出评价，并优化其填筑工艺。

Abstract: For the feasibility of subgrade fill materials, extensive laboratory compaction tests are performed on the poorly graded boulder, gravelly coral reef soils from Sanya Areas. The number of material preparation layers and levels of the compaction energy on the compaction results are examined. The feasibility of using the coral reef debris for the roadway construction and its construction techniques are also discussed in the paper.
