In some cases, the long term heaving occurred at mountain tunnels after construction, despite having invert arch. As a countermeasure, we proposed the flow to inhibit the long term heaving that indicate invert arch structure as to geological condition and convergence and it applied to all mountain tunnels that under construction since 2014. But currently, there are a few cases that apply to the flow, and there is a small amount of data to check the effect of the flow. In this paper, we make numerical analysis model that can simulate heaving for real. And we analyze by using the model and considering invert structure, invert support, early closure as parameters to verify the inhibitory effect against long term heaving.
