摘要
在偏压隧道的施工步序的设计过程中,如何合理的选择施工工法以及衬砌支护的侧重点是此类工况的难点要点,结合相关工程设计实例,运用有限差分软件对设计方案进行数值模拟,对两种施工方案进行比较,从而得出一些关于工法与支护结构优化的结论,为后续此类工况下的设计提供一些参考。
In the design process of the construction steps of the biased pressure tunnel,how to choose the construction method reasonably and the emphasis of the lining support are the key points of this kind of working condition.By co MParing two construction schemes of the relevant engineering design examples and numerically simulating with the finite difference software,some conclusions about the optimization of working method and supporting structure are obtained,which can provide some reference for the design of this kind of working condition.
