Anti-seismic protection structure for bedding slope tunnel portal and construction method
The invention relates to the technical field of tunnel construction, and particularly discloses a bedding slope tunnel portal anti-seismic protection structure and a construction method. Comprising a retaining protection structure arranged on the outer side of a tunnel portal, a slope protection assembly arranged in the slope direction of the slope and located on a side slope, a cover arch system arranged at the tunnel portal and a first elastic shock-proof structure with the two ends hinged to the cover arch system and the retaining protection structure correspondingly. The cover arch system comprises a cover arch structure arranged at the tunnel portal and connected with the supporting and retaining protection structure through a first elastic shock absorption structure, and an energy dissipation assembly installed on the outer side of the cover arch structure and arranged in the axial direction of the tunnel. The invention further discloses a construction method. The anti-seismic performance of the protection structure can be improved; and the influence of the earthquake action on the tunnel structure is effectively reduced.
本发明涉及隧道施工技术领域，具体公开了一种顺层边坡隧道洞口抗震防护结构及施工方法，抗震防护结构，包括设置在隧道洞口外侧的支挡防护结构、沿边坡坡向设置且位于边坡上的斜坡防护组件、设置在隧道洞口处的套拱系统、以及两端分别与套拱系统和止挡防护结构铰接的第一弹性避震结构；所述套拱系统包括设置在隧道洞口处且与支挡防护结构通过第一弹性避震结构连接的套拱结构、以及安装在套拱结构外侧且沿隧道轴向设置的消能组件。以及公开了其施工方法；本发明能够提高防护结构的抗震性能；有效的降低地震作用对隧道结构的影响。
