| Abstract: | Jinping level 2 water tunnel engineering hydropower station is deeply buried in an area of high natural stress.The tunnel diversion of Jinping hydropower station is deep,high geo-stress.While drilling and blasting in the construction of high stress,we encountered the problems caused by rock-burst,which greatly affected the construction schedule、equipment and personnel security.We summarized the rock-burst pattern in the construction process and did some exploration.Through various forms of the field trials,we summed up the construction methods and measures to control rock burst. |
