摘要
针对高速公路隧道进出口过渡段不均匀沉降导致的跳车现象,结合千黄高速公路在服役性能与耐久性方面的要求,利用ABAQUS有限元软件建立车辆-道路-搭板结构-地基耦合振动分析模型,揭示高速交通荷载作用下道路结构及地基的动力响应特性和累积应变规律。
The vehicle jumping problem is often caused by uneven settlement of road lap plates at the entrance and exit of expressway tunnel.Taking the service performance and durability requirements of Qianhuang expressway as the case,a vehicle-road-slab structure-foundation coupled vibration analysis model was established by using ABAQUS finite element software.Furthermore,the dynamic response characteristics and cumulative strain law of road structure and foundation under the action of high speed traffic load are revealed.
