摘要(Abstract)：

利用水下控制爆破方法拆除了大源渡河中的混凝土纵向围堰。文中介绍了爆破方案选择、最大一次起爆药量的计算、钻孔与装药设计、起爆网路等 ;较详细地论述了主要的爆破安全措施。结合该工程实例 ,对纵向围堰的布置及其爆破拆除提出了几点看法。
A longitudinal concrete cofferdam was demolished by way of underwater controlled blasting. The calculation of maximum charge weight per delayed interval, the design of drilling and charging structure, initiation network and others were introduced. Main blasting safety precautions were discussed in detail. In the light of this engineering example, some views on the arrangement and blasting demolition of a longitudinal cofferdam were put forward.
