  • In this work, based on the determination of the rockfall impact energy and using the dynamic finite element numerical method, we analyzed dynamic responses of large-span shed-tunnels of mountain tunnels under rockfall impact, and investigated the characteristics of damages suffered by the shed-tunnel structure's reinforced-concrete. The impact depth time-history curve and impact force time-history curve under different conditions were presented for comparison and different buffering effects were also summarized for comparison between the common soil and the light soil on which shed-tunnels were constructed. Meanwhile, suggestions concerning the choice of backfilled soil and the propriety of its thickness were proposed. The results from our study will be valuable for the design of mountain tunnels' large-span shed-tunnels and the prevention of rockfall that may damage them.
