摘要
以民生路-杨高路立交工程的跨线桥承台为研究对象,采用三维有限元软件建立该桥承台和桩的单元模型,针对跨越运营地铁区间盾构隧道的桥墩承台特点,对此类承台设计要点进行了探讨,并建立相关模型研究承台施工开挖对地铁的影响。
According to the study object of the overpass base slab,the 3D finite element software is used to establish the element model of the bridge base slab.Aiming at the characteristics of bridge pier base slab crossing the shield tunnel of subway under operation,the article discusses the design gist of this kind of bas slab.The relative model is established to study the influence of construction and excavation of bas slab on subway.
