摘　　要：为了研究玄武岩纤维(BF)、聚丙烯纤维(PF)、陶砂(PS)这三种因素对玄武岩-聚丙烯纤维陶砂混凝土(BPPC)力学性能的影响,采用正交试验法对16组BPPC开展了抗压强度、劈裂抗拉强度和抗折强度试验。结果表明:玄武岩纤维的掺入能够显著提高BPPC的劈裂抗拉强度,最大增幅为14.22%,三种因素对劈裂抗拉强度的增强幅度优于对抗压强度和抗折强度的增强幅度;陶砂体积率是影响BPPC抗压强度的特别显著性因素,玄武岩纤维是影响BPPC劈裂抗拉强度和抗折强度的特别显著性因素。将三种因素对BPPC力学性能的影响进行了理论分析,并就正交试验结果进行了回归分析,建立了BPPC强度预测模型,预测精度较高。In order to study the influence of basalt fiber(BF),polypropylene fiber(PF)and pottery sand(PS)on the mechanical properties of basalt polypropylene-fiber pottery-sand concrete(BPPC),16 groups of BPPC are tested for compressive strength,splitting tensile strength and flexural strength by orthogonal test.The results show that:the incorporation of basalt fiber can significantly improve the splitting tensile strength of BPPC,with a maximum increase of 14.22%;the three factors are better than the compressive strength and flexural strength;the volume ratio of ceramic sand is a particularly significant factor affecting the compressive strength of BPPC,and the basalt fiber is a particular factor affecting the splitting tensile strength and flexural strength of BPPC Significant factors.The influence of the three factors on the mechanical properties of BPPC is analyzed theoretically,and the regression analysis is carried out on the orthogonal test results.The strength prediction model of BPPC is established with high prediction accuracy.
