Abstract
The weak geological structural planes such as faults are the main factors controlling the stability of the surrounding rock of the underground powerhouse cavern group.Based on the layout of the underground powerhouse cavern group in Sizhou Mountain,combined with the geological conditions of the surrounding rock,a three-dimensional model including faults and joint fissures is established to simulate the layered excavation and support scheme of the powerhouse,revealing the distribution law of the plastic zone and potential failure parts of the surrounding rock of the cavern group.The analysis results indicate that the surrounding rock of the underground powerhouse cavern group in Sizhou Mountain is stable and meets the conditions for tunnel formation.The results provide reliable guidance for subsequent construction design.关键词
