摘要
结合实际工程的设计参数及地质勘察数据,利用大型有限元软件建立模拟过江隧道开挖的数值模型,分析不同形式过江隧道在不同覆盖层厚度以及不同水位高度下的衬砌应力与隧道拱顶位移的变化规律,为类似工程设计、施工提供参考。
In this paper, the design parameters of the actual engineering work, geological survey data and finite element software are used to establish the numerical model of the river - crossing tunnel excavation to analyze lining stress and the arch top displacement, the different forms of underwater tunnel at different cover thickness and different water levels, which can provide a reference to design and construction of similar tunnel structures.
