摘　　要：通过对青溪水电站坝基开挖进行的光面爆破试验研究，表明上覆保护层厚度及孔距布置直接影响到基面的工程质量，得到满足建基面质量控制的上覆保护层厚度范围及孔距布置要求。The experimental research on smooth blasting carried out in dam foundation excavation of Qingxi Water Power Station indicates that the thickness of upper protective layer and space arrangement between holes throw direct influence on the engineering quality of foundation surface. The thickness of upper protective layer and space arrangement between holes required to meet the demand of quality control of the foundation surface are obtained.
