水泥稳定碎石混合料无侧限抗压强度的影响因素分析

以水泥稳定碎石的抗压强度参数取值为研究方向，通过收集既有水泥稳定碎石混合料抗压强度试验数据，建立强度数据库，在不同保证率下取得各参数代表值，对比分析试件成型方式、集料级配类型、养生龄期、水泥剂量等不同影响因素与水泥稳定碎石抗压强度的关系，利用数学回归方法，建立不同养生龄期、水泥剂量条件下的预测方程。经验证，所建立强度对数模型具有较高的拟合精度，可为路面结构设计与性能预估提供取值依据。

Analysis on Influence Factors of Unconfined Compressive Strength of Cement Stabilized Gravel Mixture

Taking the compressive strength parameter selection of cement stabilized gravel as the research direction, by collecting the test data of the compressive strength of the existing cement stabilized gravel mixture and establishing database of strength, the representative values of various parameters under different assurance rates are obtained, the relationship between different influence factors such as the specimen forming method, type of aggregate gradation, curing age, cement dosage, etc. and the compressive strength of the cement stabilized gravel is compared and analyzed. Using the mathematical regression method to establish prediction equation under different curing ages and cement dosage. It is verified that the established strength logarithm model has higher fitting precision, which can provide value basis for pavement structure design and performance forecast.
