【摘要】 结合铁道部震区隧道标准设计及隧道震害调查中遇到的问题,对铁路隧道水平地震力计算进行深入研究,对传统震区隧道水平地震力计算的思路和方法提出不同意见,并计算验证水平地震力的影响程度,认为震区隧道设计中,水平地震力不是隧道衬砌设计的控制性因素,不需要因地震力而增加钢筋配置量,但考虑延性要求,需要考虑构造抗震措施。更多还原

【Abstract】 With reference to the design standards by MOR for tunnels in earthquake region and the problems investigated after earthquake,this paper studies intensively the horizontal seismic force of the tunnel generated by earthquake,puts forward different ideas about the traditional concept and method of calculating the force and defines the effect of horizontal seismic force.The results show that horizontal seismic force is not the controlling factor in the design of tunnel lining,and no additional reinforcement is required on account of seismic force.But the seismic structural measures are necessary to account for structural ductility.更多还原
