摘要

为研究公路和轨道交通荷载共同作用下隧道的动态响应，本文引入微观交通流模型中的元胞自动机模型来模拟公路车流荷载，利用多体动力学模型来模拟轨道车辆荷载，以上海某公铁两用隧道为例建立隧道-土体系统的三维动力有限元模型，对公路和轨道交通载荷单独作用及共同作用时的隧道动力响应进行分析，获得了公铁两用隧道的动力响应规律，为其设计提供参考。

Abstract

In order to study the dynamic response of tunnel under traffic flow loads and train loads, the cellular automaton model is introduced to simulate the road traffic flow loads，and the multi-body model is used to simulate the train loads. Taken a combined rail-cum-road tunnel in Shanghai as an example, a three dimensional dynamic FEM model of a tunnel-soil system is established and the dynamic response properties of the tunnel are obtained under different loads, which could provides reference for the design of combined rail-cum-road tunnel.
