摘　　要：采用正交试验设计方法,对16种集料级配的水泥稳定碎石试件分别进行无侧限抗压强度试验、劈裂强度试验和干缩试验,探求集料级配组成对水泥稳定碎石抗压强度、劈裂强度及干缩应变指标的影响规律,为设计和施工提供参考。Orthogonal experiment design method is adopted to conduct lateral confinement free compressive strength test, tensile splitting strength test and dry shrinkage test to 16 different aggregate gradation cement stabilized debris test samples, so to explore the rules of influence by aggregate gradation to compnessive strength, tensile splitting strength and dry shrinkage strain indexes of cement stabilized debris, and so to provide reference to design and construction.

关 键 词：正交试验 水泥稳定碎石 集料级配 无侧限抗压强度 劈裂强度 干缩应变
