摘　　要：为提高微硅粉在工程中的利用率,文章研究了微硅粉掺量对水泥土性能的影响。通过冻融循环下无侧限抗压强度试验结果表明:水泥土中掺入微硅粉不仅能有效提高其强度,其在冻融循环下的强度增强更加明显。上述研究不仅为提高水泥的抗压强度提供了可行方案,还为微硅粉水泥土在季节冻土地区的应用提供一定的技术支持。In order to improve the utilization rate of microsilica powder in engineering applications,this paper stud⁃ies the influence of microsilica powder on mechanical properties of cement-soil.The results of the unconfined com⁃pressive strength test under the freeze-thaw cycle show that the addition of microsilica fume into the cement soil can not only effectively improve its strength,but its strength under the freeze-thaw cycle is more obvious.The above research not only provides a feasible method to improve the compressive strength of cement-soil,provides certain technical support for the application of silica fume cement soil in seasonal frozen soil areas.
