摘要:
针对传统地震动力响应数值分析方法存在应力响应性能较差的问题，提出一种隧道衬砌结构断裂粘滑段地震动力响应数值分析方法，对隧道衬砌结构断裂粘滑段进行地震动力响应数值分析。利用动力数据ICP采集系统采集模拟中的动力数据，并通过振动台动力振动模型，对隧道衬砌结构断裂粘滑段在地震波下受到的影响进行模拟，根据模拟结果，获取隧道衬砌结构断裂粘滑段地震动峰值加速度的具体变化规律，从而获得断裂粘滑段的地震动峰值加速度，构建隧道衬砌结构断裂粘滑段的地震动力响应数值分析模型，对隧道衬砌结构断裂粘滑段进行地震动力响应数值分析。为了证明该方法的应力响应性能较强，将传统地震动力响应数值分析方法与该方法进行对比实验，实验结果证明该方法的地震动力响应数值分析方法更加平稳，也就是该方法的应力响应性能优于传统地震动力响应数值分析方法，更适合进行隧道衬砌结构断裂粘滑段的地震动力响应数值分析。
Abstract:
In order to solve the problem of poor stress response performance in traditional numerical analysis method of seismic dynamic response，a numerical analysis method of seismic dynamic response for the fracture stick-slip section of tunnel lining structure is proposed，and the corresponding numerical analysis of seismic dynamic response for the fracture stick-slip section of tunnel lining structure is carried out. The dynamic data in the simulation are collected by ICP acquisition system，and the influence of the fracture stick-slip section of tunnel lining structure under seismic wave is simulated by the dynamic vibration model of shaking table. According to the simulation results，the specific variation law of the peak acceleration of the ground motion in the fracture stick-slip section of tunnel lining structure and the peak acceleration of the ground motion in the fracture stick-slip section are obtained. In this paper，the numerical analysis model of seismic dynamic response for the fracture stick-slip section of tunnel lining structure is constructed，and the numerical analysis of seismic dynamic response for the fracture stick-slip section of tunnel lining structure is carried out. In order to prove that the method has better stress response performance, the traditional numerical analysis method of seismic dynamic response is compared with this method. The experimental results show that the numerical analysis method of seismic dynamic response of this method is more stable，that is, the stress response performance of this method is better than that of the traditional numerical analysis method of seismic dynamic response，and it is more suitable for the numerical analysis of seismic dynamic response of the fracture stick-slip section of tunnel lining structure.Keywords: Tunnel；Lining structure；Fracture stick-slip section；Seismic dynamic；Response numerical analysis
