摘　　要：水工建筑物过流面受含砂水流的冲刷磨蚀,常规水工抗冲磨混凝土使用寿命较短,结构修补频繁。通过水下钢球法试验和工程现场洪水冲刷检验,结果表明,常温养护条件下,C130超高性能混凝土的抗冲磨性能约为常规掺聚丙烯纤维C30水工抗冲磨混凝土的8倍。采用抗冲磨超高性能混凝土作为水工建筑物过流面的结构功能层,有助于延长水工结构使用寿命,减少修补频次,保障运行安全,降低全寿命周期成本。The overflow surface of hydraulic structures being subject to abrasion of water-sand flow,with conventional anti-abrasion hydraulic concrete,usually shows short service life and needs frequen repairs.The results of underwater steel ball test and on-site post-flood inspection show that,under normal temperature curing conditions,the anti-abrasion performance of the C130 UHPC is about 8 times that of conventional C30 anti-abrasion hydraulic concrete mixed with polypropylene fibers.The use of abrasion-resistant ultra high performance concrete as the structural functional layer for the overflow surface of hydraulic structures,can extend the service life,reduce repair frequency,ensure operational safety,and then lower the life cycle cost of hydraulic structures.
