Abstract During tunnelling, layered fractures occurred in the deep tunnels at the Jinping II Hydropower Station. Using numerical simulation methods and the basic theories of fracture mechanics, the mechanism of rock crack propagation influenced by the intermediate principal stress, the stress path and the principal stress axes rotation was studied. In addition, based on the analysis of the stress path and principal stress rotation of the surrounding rock mass in the test branch tunnel F during the excavation process, the mechanism of formation of layered fractures is discussed.
