摘要
以某傍山位置的偏压双联拱隧道为工程背景,利用有限元软件ANSYS模拟隧道的施工过程,给出施工过程中围岩和支护结构应力和变形的变化规律,讨论不同施工顺序对应力和变形的影响。
The finite element method is used to simulate the construction process of a twin-arched tunnel which is located near a steep slope. The variety law of stress and deformation of the surrounding rock and the supporting structure in the construction process are presented, and the effect of different construction sequences on the deformation and the stress is discussed.
