摘要
在不同的施工环境、地质条件采用微差爆破的起爆方式,能有效控制爆破震动、飞石、冲击波等不利因素对周边建筑影响。结合将乐县桃源水库工程二期左岸坝基的爆破开挖,探讨复杂环境条件下采用浅孔微差爆破的施工方法,确保爆破周边建筑、机械设备、临时设施等的安全。
In different construction environment with variable geological conditions, shallow hole and short delay blasting is adopted to control the harmful influence on surrounding buildings from blasting shake, flying stone and shock wave. Combined with the dam foundation blasting excavation by left bank of Taoyuan Reservoir located at Ji- angle County, the author discussed the construction method of shallow hole and short delay blasting which shall be adopted in complicated environment to guarantee the safety of surrounding buildings, machine and temporary facilities.
