摘　　要：小湾水电站泄洪洞在泄洪时具有高水头、高流速、泄量大的特点,对混凝土冲刷力强,容易产生空蚀破坏。通过合理选择浇筑措施、优选配合比、有效的温度控制以及合理的养护,目前,泄洪洞各方面质量均满足要求,且未发现裂缝。泄洪洞抗冲耐磨混凝土施工及质量控制的成功,为减小泄洪洞过流面空蚀和抗冲耐磨提供了保障。As the high head, high velocity and large flow of flood discharge, the concrete of spillway tunnel in Xiaowan Hydropower Station is easy to be damaged by cavitation. By reasonable pouring, mix proportion optimizing, effective temperature control and reasonable curing, the concrete quality of spillway tunnel is guaranteed and no crack found. The successful concrete construction and quality control provides guarantees on reducing surface cavitation and increasing abrasion-resistance capacity.
