摘要(Abstract)：

概述了三峡三期碾压混凝土 (RCC)围堰拆除爆破方案设计的总体思路 ,并较详细地研究了一、二阶段横向围堰和纵向围堰拆除的爆破方案。经过比较和分析 ,推荐了各部位的优化方案。针对所推荐的方案 ,论述了爆破参数、起爆网路和安全防护的设计。此外 ,对各推荐方案的主要技术经济指标进行了预测 ,并简述了需进一步开展的研究工作
A general thinking to blasting plan for demolishing third stage roll compact concrete(RCC)cofferdams in the Three Gorges was outlined and the blasting schemes for demolition of longitudinal cofferdam and first phase and second phase transverse cofferdams were researched in detail After the comparison and analysis,the optimal blasting scheme for every section was recommended For the blasting schemes recommended,the designs of blasting parameters,firing circuit and safety protection were discussed In addition,main techno economical indexes of every recommended scheme were predicted and the research work to be required further was briefly described
