摘要
讨论双圆盾构隧道(DOT:Double-O-Tube)施工时,管片衬砌拼装内力的有限元计算。包括整个拼装过程的有限元模拟方法,采用三维实体单元模拟隧道管片衬砌在工程中不同工况下的内力变化。结合双圆隧道的工程参数,进行实际问题的计算,为目前双圆隧道管片衬砌内力计算探索出一条计算模式。
The finite element analysis of double-O-tube （DOT） shield tunnel for the internal forces in the assembling segment lining was provided. Three dimeusioual entity elemetn was recommended to model the tunnel lining in order to ensure the deformation results during the whole assembling process. A practical problem was analyzed to show the performance of the proposed numerical procedures by using the actual construction parameters.
