Abstract Reasonable supporting design can effectively control and avoid rock burst disaster under the risk of rock burst，reduce the loss caused by rock burst，and ensure the safety of the staff and project. Different from ordinary high stress damage，rock burst has its special trigger mechanism and control strategy. In the engineering background of the world′s largest deep buried tunnel of Jinping II hydropower station，based on the complexity of trigger mechanism of different type rock burst，discussed the question of supporting unit selection. According to two prominent features of fracture and brittle-ductile-plastic conversion of deep buried marble，respectively from three aspects of damage depth and carrying ability，energy release quantity and energy absorption ability and deformation and deformation ability，the supporting ability under the condition of rock burst is estimated，and the features and functions of supporting unit are analyzed in detail. Then the suitable supporting unit selection method under the condition of rock burst is proposed. The burst damage characteristics of surrounding rock are deeply analyzed by the discontinuous mechanics method. Finally，the support optimization design method under the condition of rock burst is discuss. The relevant research results and practical experience can provide a reference for similar engineering design.

Key words： rock mechanics rock burst deep buried tunnel supporting design Jinping II hydropower station
