摘　　要：水泥稳定碎石材料已被较多地应用于路面基层,但在港口工程中鲜有应用。结合某港口码头堆场基层施工,进行水泥稳定碎石生产配合比设计的研究,分别从目标配合比确认、集料生产级配调试、水泥含量-EDTA关系曲线、延迟曲线和强度-含水率曲线等几个方面阐述港口工程水泥稳定碎石材料生产配合比设计过程,确认了施工阶段集料级配、水泥剂量、含水量、碾压延迟时间等生产参数,为该堆场的施工提供了理论依据。The cement stabilized aggregate has been widely used in the pavement base,but it is rarely used in port engineering.Combining with a port yard base construction,we study the production mix ratio design of the cement stabilized aggregate,expound on the design process of the production mix ration of the cement stabilized aggregate from the confirmation of the target mix proportion,grading adjustment of the aggregate production respectively,cement content-EDTA relation curve,delay curve and strength-water content curve,and confirm the production parameters including aggregate gradation,cement dosage,water content,as well as rolling delay time,providing a theoretical basis for the construction of the yard.
