摘　　要：预留岩坎挡水施工方案可有效地降低临时挡水建筑物的规模和投资。岩坎拆除一般受坎外水位影响较大,同时岩坎一般距主体建筑结构及其它设施较近,拆除爆破安全控制要求较高。文章针对某水库内新建取水泵站预留岩坎爆破拆除方案进行了分析和研究,制定了较详细的岩坎爆破拆除方案,并提出了爆破工艺和安全控制措施。The water retaining construction scheme with reserved rock bar could effectively decrease the scale and cost of temporary water retaining structure.The rock bar demolishment is greatly affected by outside water level and the higher safety blasting control is required because of the close distance from the rock bar to the main structure body and other facilities.The paper studies and analyzes the blasting demolishment scheme of reserved rock bar for the new pumping station of some a reservoir,makes detailed blasting scheme and provides blasting technique and safety control measure.
