The excavated slope is 170m in height so it is important for controlling blasting quality.Based on construction characteristies of exeavation and blasting in the inlet area the relative quality control standard on excavation and blasting is established.By adopting a series of quality controlling measures the excavation and blasting quality is controlled effectively from two aspects of stability of the high slope and the quality of the excavated slope surface. Key words:Xiluodu Hydropower Station:left bank:inlet:excavation and blasting ...
