| Abstract: | Under the consideration of the engineering geological condition of Dahuashui Hydropower Station, the pre-splitting blasting technology and reasonable construction method are adopted for the excavation of the dam foundation in accordance with the analysis on the rock strata therein, in which the design of the blasting parameters and powder charging structure as well as the angle control and the height of the excavating steps are particularly determined, and then better splitting effect is got for the slope excavation and the quality requirement of the construction is satisfied as well. |
