【摘要】 以天津地铁1号、2号线为实例,利用有限元数值方法,对地震荷载作用下隧道结构的二维弹塑性动力响应进行模拟,通过地震作用对隧道所产生的应力值、位移值等得出地铁隧道受地震力作用时的危险点,为今后的隧道设计提供依据。更多还原

【Abstract】 In this paper,with the example of Tianjin No.1 subway and No.2 subway,using the finite element method,on the subway train tunnel structure under vibration load dynamic response of two-dimensional simulation of plastic.Through the earthquake generated by stress,displacement,etc.come under the train tunnel when the earthquake force the danger point,for the future provide the basis for tunnel design.更多还原
