【摘要】 隧道结构内力是衬砌结构检算的依据。论文采用ABAQUS软件对隧道洞身在纵向正弦地震波作用下,对结构内力的效应情况进行了分析。结果表明:结构内力在静态时的正负情况,影响其在动力状态下的响应规律。同时,静力分析的主控检算断面仍然是动力分析的检算断面,设计应结合动力分析内力时程曲线的内力极值,开展结构检算。更多还原

【Abstract】 Tunnel structural internal force is the basis for calculation of lining structure.This paper analyzes the effect of tunnel structural internal force under longitudinal sinusoidal earthquake wave with ABAQUS software.The conclusion shows that the negative or positive of structural internal force under static state will influence its response rule under dynamic state.Meanwhile,the main control calculation section for static analysis is still the same for dynamic analysis.Structural calculation shall be carried out combined with the extreme value of internal force time-travel curve for dynamic analysis in design.更多还原
