Abstract:The energy dissipation constitutive model for complex surrounding rock has been estabilished.The element damage,plasticity and tension fracture are considered in the formula of energy dissipation.Three principles of construction process mechanics,energy transformation and analysis of loading change in time and space for excavation and supporting of rock caverns have been presented.An application computation for comparing four schemes of construction order optimazation related to the rock cavern stability of Xiluodu hydraulic power project have made as well.The optimized construction scheme was obtained.
Keywords:energy dissipation  constitutive equation  principle of construction process mechanics  stability analysis of underground caverns  optimization of construction order
