摘　　要：反应位移法是一种输入一维土力学参数的地震反应分析方法。文章结合广州地区某地铁地下车站工程的计算实例,简单介绍了反应位移法的理论基础和计算过程。根据相关规范、论文研究给出的计算方法,利用软件建立平面框架的应变分析模型,对地震作用、准永久组合的分析结果进行比较。分析结果表明,地震作用在常规矩形断面地铁车站内力计算中不起控制作用。The response displacement method is a seismic response analysis method that inputs one-dimensional soil mechanical parameters.Based on the calculation example of an underground subway station project in Guangzhou,this paper briefly introduces the theoretical basis and calculation process of the response displacement method.According to relevant specifications and calculation methods provided in the paper,the strain analysis model of plane frame is established by software,and the analysis results of earthquake action and quasi-permanent combination are compared.The analysis results show that the earthquake action does not play a controlling role in the internal force calculation of the conventional rectangular section subway station.
