摘　　要：使用水泥、石灰、矿粉等掺合料对黄河淤泥进行复合改性,测试了不同改性剂、水灰比和成型方式对淤泥试件抗压强度的影响,使用XRD衍射分析研究改性前后物相的变化,使用SEM扫描电镜观察改性前后形貌的变化。结果表明,使用水泥作为改性剂可显著改善淤泥试件的强度,加压成型的淤泥试块强度可达到浇筑成型试件的五倍以上。Compound modification by adding cement, lime, slag and other admixture into Yellow River silt, the influence of different modification agent, water cement ratio and forming method on the compressive strength of the silt specimen was analyzed. Using XRD and SEM to study the change of phase and morphology before and after compound modification. The results showed that, using cement as the modification agent can significantly improve the strength of the silt specimen, the silt specimen strength compression formed can reach more than five times of the pouring formed.
