粉煤灰路基模型材料试验研究

Experiment study of fly ash for roadbed model test

粉煤灰已经广泛地应用于高速公路的建设中。通过材料试验来确定用于粉煤灰作为地基的路基模型试验的模型材料。文章以列图表方式介绍了在本次地材料试验过程中,所做的材料试验的数据处理等,主要包括粉煤灰的应力应变关系和变形模量、粉煤灰和粘性土的配比试验、粉煤灰和珍珠岩配比试验、珍珠岩和粘性土配比试验、珍珠岩和铁配比试验、蛭石和粘性土配比试验等一系列的试验,并列表给出试验处理后的材料的变形模量。为将来用这些相关材料或做相关材料的试验的人提供一个数据的参考。

Fly ash has been widely used in highway roadbed construction. As a roadbed model test material, experiments were made. Test data were presented by using charts, and the analysis involved as following： stress-strain relationship and deformation modulus for fly ash, ratio test of fly ash and clayed soil, fly ash and perlite, perlite and clayed soil, perlite and iron pint, and vermiculite and clayed soil. As a result, the deformation modulus of fly ash was listed to be as references which maybe useful for further study.
