Assembled rigid-flexible combined buffer structure at top of anti-rockfall shed tunnel
The invention relates to an assembled rigid-flexible combined buffer structure at the top of an anti-rockfall shed tunnel, the combined buffer structure comprises a lower flexible plastic energy consumption layer and an upper rigid protection layer, and the rigid protection layer comprises a steel plate layer and a steel grating layer on the steel plate layer; the combined buffer structure coversthe top of the rockfall-preventing shed tunnel, is integrally arched and has a pre-camber, and a gap is formed between the combined buffer structure and the top of the protective shed tunnel. The structure can effectively reduce the impulse force load of falling rocks, and has the advantages of light structure, long service life, convenience in maintenance, low manufacturing cost and the like.
本发明涉及一种防落石棚洞顶部的可拼装刚柔组合缓冲结构，所述组合缓冲结构包括下层的柔塑性耗能层和上层的刚性保护层，刚性保护层包括钢板层和其上的钢格栅层；组合缓冲结构覆盖于防落石棚洞顶部，整体呈拱形，并设置预拱度，与防护棚洞顶之间形成间隙。本发明可有效降低落石的脉冲力荷载，具有结构轻型化，使用年限长，便于养护，造价低廉等诸多优点。
