Abstract
Coal gangue and fly ash have good compression resistance,shear resistance,freeze-thaw resistance,as subgrade fillers have the advantages of turning waste into treasure,energy saving and carbon reduction.Based on the volume stability,mechanical properties and thermal stability of coal-based solid waste in roadbed engineering,the project proposed five key control indicators,established the application grading evaluation criteria for coal-based solid waste filling roadbed,revealed the dynamic evolution process of gradation of coal-based solid waste particles after crushing and the micromechanical characteristics,and proposed the anti-pollution design structure of coal-based solid waste roadbed based on the law of moisture and pollutant migration.Through the solid engineering practice,the research on the key technology of large-scale application of typical industrial solid waste roadbed filling and the engineering large-scale application practice have achieved remarkable economic,social and environmental benefits.关键词
