摘　　要：分析了混凝土中掺入少量改性聚丙烯纤维对混凝土的抗裂、抗渗、抗冲耐磨等各种性能的影响。为了解决桥巩水电站船闸输水廊道由于高速水流及泥沙冲刷、磨损、侵蚀而出现的问题,设计过程中在输水廊道周边混凝土中掺入少量改性聚丙烯纤维,低掺率的改性聚丙烯纤维能有效提高混凝土的抗裂、抗渗和抗冲刷等能力。Analysis was made on the influence of low content of modified Polypropylene fiber mixture on the properties of concrete such as crack resistance,impermeability,impact and abrasion resistance.In order to settle the scouring and erosion problems from high_velocity flow and sediment for the shiplock of Qiaogong Hydropower Station,low content modified Polypropylene fiber mixture was designed for the surrounding concrete of conveyance system,effectively improving the crack resistance, impermeability and impact resistance of concrete.
