摘要:
为了解粉煤灰的工程特性及其力学性质，采用了颗粒分析试验、密度试验、击实试验和压实渗透试验，研究了某电厂粉煤灰颗粒的大小分布规律、干密度与含水率规律、压缩与渗透特性。试验结果表明：粉煤灰的颗粒分布不均匀，粒度偏粗；粉煤灰的干密度越小，渗透系数越大；击实密度对粉煤灰的含水量影响不大；较大的压实度使得粉煤灰颗粒变得更加密实、孔隙比变得更小，导致粉煤灰的渗透系数呈减小趋势。
Abstract:
In order to investigate the engineering characteristics and mechanical properties of coal ash, the size distribution laws, the dry density and moisture content laws, and the compression and penetration characteristics of coal ash particles in a certain power plant were studied based on the particle analysis test, density test, compaction test and penetration test. The results showed that the particles of coal ash have coarse granularity and uneven distribution. The smaller the dry density, the higher the penetration coefficient. The compaction density has little influence on sample moisture. The larger compactness makes the coal ash particles denser and the pore ratio smaller, which results the decrease tendency of penetration coefficient.
