Abstract:
The excavation for the rock anchored beams under high ground stress and low compressive rock strength conditions is difficult. Furthermore, the rock anchored beams are prone to cracking after concrete casting. The excavation for the rock anchored beams, the parameters of advance support, the construction techniques for highstrength anchors and the concrete casting time and methods are presented in detail, with the construction of the rock anchored beam of Jinping I Hydropower Station as an example. In the end, successful construction has been achieved.
Key words: Jinping I Hydropower Station, high ground stress, low compressive strength, rock anchored beam, construction
