摘　　要：填料作为形成高填方机场场地的重要载体,种类多、方量大、工程性质复杂。根据颗粒分析试验,场区内填料属级配良好的填料。采用超粒径处理方法,得出了两种填料的击实指标。研究了粗料含量对最大干密度指标的影响,得出了爆破碎石填料不同粗料含量对应最大干密度推荐值。针对大规模施工,提出了填料不同压实度对应固体体积率控制指标建议值。通过试验段大量现场实测资料,得出了各施工阶段填料密度数据、场地土挖填系数。In airport high-fill project, filling has the characteristics of great variety, quantity and complex properties. Filing in the site is well-graded soil according to particle size analysis. Based on treating soil over grain size, compaction test standard of two kinds of filling is defined. The corresponding recommended value of maximum dry density of blasted gravel with different influence granular content is acquired by study. Controlled standard of solid-volume ratio for weathered rock and bloken rock is put forward for large-scale construction. Dry density of filling in different construction stage, coefficient of excavation are acquired through actual data.
