摘要

共和新路一体式高架是国内首次采用高架地铁与高架道路相结合的综合高架交通工程。目前国内外对这种结构的抗震设计和分析尚缺少成熟经验。共和新路一体式高架动力计算模型的正确建立是地震反应分析的基础和关键。针对共和新路一体式高架结构的抗震特点,模拟轨道以及后继结构的影响,考虑桩土相互作用,桥面铺装、橡胶支座的作用,建立动力计算模型,并对其进行了评价以及动力特性分析。
The urban viaducts with a double deck in Shanghai-Gonghexin Road Viaducts are now under construction. It is a synthesized viaduct traffic engineering that firstly combines urban arterial highway with urban light railway at home. Its upper deck is urban arterial highway with six lanes and the lower deck is urban light railway system with two lanes. For now there are few experiences in the seismic design and analysis of the urban viaduct at home and abroad. It is a basis and important task to give correct analysis model of the structures for seismic analysis. The effects of the rail and the adjoining structure, the pile-soil-structure interaction, the deck pavement, and the elastomeric bearings are considered according to the seismic design characteristics of the structure, and then the analytical model for dynamic calculation of the structure is built. In the end, evaluation and dynamic characteristic analysis of the structure are performed.
