Rigidity-damping coupling parameter control-based high-intensity area mountain tunnel lining damping layer design method

The invention discloses a high-intensity area mountain tunnel lining damping layer design method based on rigidity-damping coupling parameter control, and belongs to the technical field of tunnel design. The invention relates to the field of tunnel shock absorption layer design under the earthquake action, in particular to a shock absorption layer design method considering tunnel structure rigidity-damping coupling and structure cooperative deformation under the earthquake action. According to the method, a tunnel anti-shock absorption structure under the earthquake action serves as a research object, the viscoelastic connection relation of surrounding rock-primary lining-shock absorption layer-secondary lining is considered, a shock absorption layer forced vibration response function is established according to the dynamic vibration theory, and cooperative deformation of surrounding rock-primary lining-shock absorption layer-secondary lining of a tunnel under the earthquake action is achieved; and then the o
