摘　　要：结合乌鲁瓦提水利枢纽泄洪排砂洞衬砌冲蚀混凝土修复工程实际,运用高性能混凝土的理念,优选原材料,复掺硅灰、矿渣微粉配制出高抗磨性的混凝土。按推荐的配合比制备的混凝土,坍落度为83 mm和197 mm,相应抗压强度可达91 MPa和81 MPa。配合正确施工措施,修复工程顺利完建并经受多年运行的考验。文中提及到的配制原则和规律在多个抗冲磨混凝土工程中推广应用,都取得成功和印证。The high performance concrete （HPC） was used in rehabilitation works of discharge flood and sediment sluice tunnel of Uruwati reservoir. The HPC was prepared by silica fume and slag powder according to recommended mix proportion. The slumps of the HPC were 83 mm and 197 mm while the compressive strength was 91 MPa and 81 MPa. The project which used the HPC has run normally for several years. The mixing principles of the HPC have been used successfully in some abrasion resistance concrete.
