摘要:
The largescale diversion tunnel of Baihetan Hydropower Station has complex geological conditions, thus various problems of rock mechanics appeared during the process of excavation. Typical damage and fracture mechanics are analyzed in depth, including the collapse along weak rock joint, stresscontrolled spalling, failure modes of fractured rock mass, relaxation damage of fractured rock columnar joints, localized stress affected by structural surfaces and stresscontrolled problems of superior fracture combinations. Engineering countermeasures are also summarised, which includes supporting measures, construction methods, supporting time, and monitoring and feedback methods for different types of failure. Through these measures, rock mechanics problems are successfully solved. Stability control of the surrounding rock of underground caverns under complicated geological conditions are achieved, ensuring successful completion of the enormous diversion tunnel of Baihetan.
