Rockfall impact resistant shed tunnel structure
The invention provides a rockfall impact resistant shed tunnel structure capable of reducing vault bending moment and improving rockfall impact resistance of a shed tunnel, and relates to the technical field of highway tunnel protection. The rockfall impact resistant shed tunnel structure comprises a bent plate, a rockfall baffle, stand columns and an earth-rock backfill layer, the bent plate is arranged on the side close to a mountain body, and the stand columns are arranged on the side away from the mountain body and connected with the bent plate. The structure further comprises a concrete layer. The bent plate comprises a body section located on the inner side of the stand column and an overhanging section extending to the outer side of the stand column, and the rockfall baffle is arranged at the outer end of the overhanging section. The safety of the shed tunnel can be improved.
本发明是提供一种能够减小拱顶弯矩，提高棚洞抗落石冲击能力的一种抗落石冲击棚洞结构，涉及公路隧道防护技术领域。一种抗落石冲击棚洞结构，包括曲板、落石挡板、立柱以及土石回填层，所述曲板设置在靠近山体侧，所述立柱设置在远离山体侧，并与所述曲板相接，还包括混凝土层；所述曲板包括位于所述立柱内侧的本体段和延伸至所述立柱外侧的悬挑段，所述落石挡板设置在所述悬挑段外端部。本发明可以提高棚洞的安全性。
