针对枕头坝一级水电站库区306省道复建公路部分路段路基宽度不足，且与仍处运行状态的永乐电站相距较近的特点，对比决定采用贴坡结合局部开挖的方案对复建公路进行扩宽施工。详细介绍了爆破开挖中各项爆破设计参数的选取，以及起爆网络和装药结构的设计。实践表明，采用精心设计的施工方案，并遵循“小药量，弱爆破，多循环”的控制原则，能将爆破开挖施工的风险降到最低。

The road foundation width of partial reconstructed S306 road in the reservoir area of Zhentouba I Hydropower Station is insufficient and near the Yongle Hydropower Station. So the road re-construction scheme of slope lining and local excavation scheme was adopted. This paper introduced the selection of blasting parameters, initiation network and explosives charge struc-ture design etc. in detail. The practice showed that adopting the construction scheme and obeying the control principles of"small explosives amount, weak blasting" can reduce the blasting risk to the maximum range.
