摘要
反应位移法考虑了地层和结构的相互作用关系与地下结构地震响应的特点,能够较真实地反映隧道在地震荷载作用下的受力特征,是一种有效的隧道抗震计算方法。概述盾构隧道反应位移法的基本原理,使用实例系统阐述了该方法的计算流程,以期推动反应位移法在盾构隧道抗震分析中的应用。
The response displacement method takes into account the interaction between the stratum and the structure and the characteristics of the seismic response of the underground structure. It can more realistically reflect the force characteristics of the tunnel under the action of earthquake loads, and is an effective seismic calculation method for the tunnel. In this paper, the basic principle of the response displacement method for shield tunnel is summarized, and the calculation process of the method is systematically described with an example, in order to promote the application of the response displacement method in the seismic analysis of shield tunnel.
