摘要为利用显示非线性有限元法分析地铁交会工况对南京某大型单洞双线隧道的影响，基于拟实建模方法，在LS-DYNA环境下建立了地铁车辆-单洞双线隧道-土体耦合系统的全三维有限元计算模型。模型非常接近真实情况，使用了接触方法来模拟轮轨之间，衬砌与土体之间的动力相互作用，使用了人工边界来模拟无限区域，还考虑了水压和土体预应力。对双车交会工况进行计算分析，得到单洞双线隧道在交会工况作用下的动力响应规律。结果表明：地铁交会产生的应力响应和位移响应都属于很小量级，隧道在交会工况下是稳定的。结果能为此类隧道的设计提供参考。

Abstract：In order to apply explicit non-linear finite element method to simulate nonstop crossing of opposite subways in a single bore tunnel, a vehicle-tunnel-soil coupled three-dimensional finite element model was established using LS-DYNA based on the virtual-reality modeling. The model was very close to the real situation, the interaction between wheel and rail and between tunnel and soil was simulated by contact method, the bottom and side boundaries of the surrounding soil were modeled by the viscous-elastic artificial boundary, water pressure of the soil and the initial stress of the vehicle-tunnel-soil were also considered. After numerical analysis, the dynamic response properties of the tunnel was obtained, the results indicated that the stress and displacement resulted from the nonstop crossing of opposite subways in a single bore tunnel were small magnitude response, and that the tunnel in such condition was stable. They provided a reference for design of such kind of tunnel.

Key words： explicit finite element method train dynamic load nonstop crossing of opposite subways a single bore double line tunnel dynamic response
