摘　　要：为探究水胶比、粉煤灰掺量以及沙漠砂替代率对沙漠砂混凝土劈裂抗拉性能的影响,采用正交试验设计来进行劈裂抗拉强度试验研究。结果表明:在掺加粉煤灰与沙漠砂的情况下,水胶比为0.48、粉煤灰掺量为30%、沙漠砂取代率为30%时混凝土劈裂抗拉强度达到最大值,并根据同批次的抗压度值与抗拉强度值回归出二者之间的函数关系式。In order to explore the influence of water-binder ratio,fly ash content and desert sand substitution rate on the tensile strength of desert sand concrete,orthogonal test design was adopted to conduct the splitting tensile strength test research. The results show that when fly ash and desert sand are added,the tensile strength reaches the maximum value when water-binder ratio is 0. 48,fly ash content is 30% and when the substitution rate of desert sand is 30%,the splitting tensile strength of concrete reaches the maximum value and the functional relationship between them is derived according to the tensile strength value and the tensile strength value of the same batch.
