摘　　要：针对卡洛特水电站溢洪道爆破开挖施工中的不均质岩体及含水岩层大块率高、根底严重等问题,结合混凝土浇筑与爆破开挖施工作业长期并存等施工特点,通过对前期爆破效果和施工措施进行研究分析,对钻孔参数、炸药、装药结构、网络参数、微差时间等提出有针对性的优化措施,并应用于施工现场,取得了良好的爆破效果。During the blasting excavation of heterogeneous rock mass and water-bearing rock stratum in the spillway of Karot Hydropower Station,problems such as high boulder rate and serious toe left are observed.Considering the long-term coexistence of concrete pouring work and blasting excavation construction,targeted optimization measures are proposed in drilling parameters,explosives,charging structure,network parameters,and millisecond time with the analysis on preliminary blasting effects and construction measures.The measures are then applied to the construction site and satisfactory blasting effects are obtained.
