摘　　要：三板溪水电站溢洪道拟从2号掺气槽往下泄槽段至挑流表层增设60 cm抗冲耐磨混凝土,为此,对掺纤维抗冲耐磨混凝土与普通抗冲耐磨混凝土的性能进行了对比研究。研究成果表明,在抗冲耐磨混凝土中掺入适量的改性聚丙烯纤维,可有效提高混凝土的抗渗透能力、抗裂能力,适当增强混凝土的抗冲磨强度,在同一设计强度等级下,可降低混凝土的绝热温升值。试验成果可为工程使用改性聚丙烯纤维提供参考。The spillway surface from the No.2 aeration tank down to the deflector of Sanbanxi Hydropower Station will pour abrasion-resistant concrete with a thickness of 60 cm.The properties of abrasion-resistant fiber-reinforced concrete and ordinary abrasion-resistant concrete are compared.The results show that the abrasion-resistant concrete mixed with appropriate amount of modified polypropylene fiber can improve the impermeability,crack resistance and abrasion strength,and in the same designed strength grade,the insulating concrete temperature rise can be lowered.The experimental study can be as reference for the adoption of modified polypropylene fiber in abrasion-resistant concrete.
