摘要
旨在研究明挖区间上跨地铁区间的施工过程,结合施工过程中采取的措施,建立三维有限元模型,通过模拟分析,得出既有线区间结构的受力情况、变形特征、沉降数据等结果,研究明挖区间上跨施工对既有区间的影响,为其他类似工程提供借鉴和参考。
The purpose of this paper is to study the construction process of the open-cut interval crossing the existing interval,combined with the support measures taken in the construction process,established the three-dimensional finite element model,through the simulation analysis,obtained the results of stress,deformation characteristics and settlement data of the existing line interval structure,researched the influence of the upper span construction of open cut interval on the existing interval,provide reference for other cases.
