摘　　要：为了研究土体中掺入土壤固化剂的加固效果,文章依托实际项目设计不同掺量固化剂配合比试验,通过无侧限抗压强度试验确定最佳配合比,并结合现场沉降监测数据分析固化剂稳定细砂土实际应用效果。研究表明:最佳配合比为固化剂含量0.03%,水泥含量6%;通过现场沉降监测,验证了固化剂稳定细砂土实际应用的合理性。固化剂稳定细砂土具有较好的实用工程价值,研究成果可为指导实际工程提供一定参考。In order to provide theoretical reference for the engineering application of soil curing agent,the reinforcement effect of curing agent on soil was studied.Based on the actual project,different dosage curing agent mix ratio tests were designed,and the optimal mix ratio through unconfined compressive strength tests was determined.Combined with on-site settlement monitoring data,the practical application effect of stabilized fine sand soil with curing agent was analyzed.Research shows that the optimal mix ratio is0.03%curing agent content and 6%cement content.Through on-site settlement monitoring,the rationality of the practical application of stabilized fine sand soil with curing agent was verified.The stabilized fine sand soil with curing agent has good practical engineering value and can provide certain reference value for guiding practical projects.
