大桑园水电站引水隧洞光面爆破技术

Smooth Blasting Technology of Intake Tunnel in Dasangyuan Hydropower Station

合理的选择光面爆破技术参数，可以明显减少对围岩的扰动和破坏，保护围岩的完整性。详细介绍了在不良地质条件下，通过合理选择光爆参数取得了良好的爆破效果，对类似工程有借鉴作用。

The reasonable selection to smooth blasting parameter is useful for reducing the disturbance and destroy to the surrounding rock and keep its stability. It introduced the parameter selection in smooth blasting in the unfavorable geological conditions and the blasting effect is analyzed.
