摘　　要：利用青岛热电厂的粉煤灰,在做了大量试验的基础上,全面分析了粉煤灰的化学成份、物理性质、以及压缩性、击实性、渗透性、抗剪强度等工程性质后指出:粉煤灰属于粗粒土的C级填料,可用它来作路堤填料;粉煤灰又是轻质材料,用于软弱地基上筑堤尤具优越性。并推荐了这一特殊填料的施工方法和注意事项。Based on a lot of tests for flyash from Qingdao Heat and Power Plant,the chemical composition,physical properties as well as the technical properties of flyash such as compressibility,compactibility,permeability and shearing strength are analyzed comprehensively in this paper. It is pointed out flyash may be included in class c of granular filler and can be used as the filler of railway embank'ments.Being lightweight material,flyash is especially, preferable in filling embankments on weak foundations. Construction methods and notes are also recommended for this special filler.
