摘　　要：以不同级配的水泥稳定类混合料为研究对象,对其干密度和7d无侧限抗压强度指标与含水量的关系展开研究,分析了水泥稳定类混合料的干密度与抗压强度的关系。分析结果表明:最大干密度对应着最佳含水量,其波峰较为明显。水泥稳定碎石混合料的最大抗压强度对应的含水量是一个区间。随着干密度的增加,混合料的抗压强度逐渐增加。当干密度达到一定值时,抗压强度急剧减小。之后,混合料的抗压强度继续增加。To take different gradation of cement stabilized mixture as the research object,the relationship between dry density and 7-day unconfined compressive strength index and water content was studied.The relationship between dry density and compressive strength of cement stabilized material is analyzed.The results show that the maximum dry density corresponds to the optimum water content,the peak is obvious.The maximum compressive strength of cement stabilized crushed stone mixture is a section of interval.With the increase of dry density,the compressive strength of the mixture increases gradually,and the compressive strength decreases sharply when dry density reaches a certain value.Then,the compressive strength of the mixture continues to increase.
