In-situ stress measurement and rockburst possibility in deep tunnel at a hydro-power station

摘要：

To study the relation between stress and rockburst during tunnel excavation at a hydro-power station, in-situ stress measurements are carried out by hydraulic fracturing method. the maximum compression stress and minimum compression stress within the tunnel cross—section are obtained by stress analysis. The possibility of rockburst is analyzed with rockburst criterion, and provided the scientific basis and technological support for the design and construction of the tunnel engineering.
