| Abstract: | As the geological condition for the rock anchored beam of the underground powerhouse of Jinping-II Hydropower Station is poor,the effective construction measures such as deep hole pre-splitting and zoning excavation along the protected layer,adding locked anchor-bars at the lower part of the declined table,advanced supporting with high-strength resin anchor-bars,advanced grouting etc.are adopted therein,and then better construction effect is obtained as well. |
