Auxiliary tunnels of Jinping Ⅱ hydropower station are deeply buried. Rock burst under high geo-stress is one of the main problems to be taken into account. With the statistical data of the rock burst in the auxiliary tunnels and the in-situ stress and the mechanical properties of the rock
risk of rock burst in the auxiliary tunnels is analyzed by using different indexes. In addition
the prevention and cure methods of rock burst in the auxiliary tunnels are discussed. The results can provide basic support for rock burst estimation and prevention in the process of construction of four diversion tunnels in Jinping Ⅱ hydropower station.
