%X The distance between upper plug and lower plug affects the energy dissipation capacity of multi-stage plug discharge tunnel. In the present paper, the reasonable distance between the upper plug and the lower plug in multi-stage plug discharge tunnel is researched by numerical simulations. Result shows that when the contraction ratio is in the scope of 0.4-0.8, a reasonable distance between upper plug and lower plug equal to or more than 5.7<i>D </i>would guarantee the full display of plugs in different stages.
