摘要
公路隧道洞口段受地形与位置的限制,工程中不可避免出现高陡边仰坡。隧道洞口施工改变了原有山体的平衡,易诱发洞口高陡边坡的滑坡、崩塌等地质灾害。依托凤凰山隧道工程对其左右线的进、出口边坡进行了稳定性分析与安全评价,为隧道工程的安全提供技术保障,对类似隧道洞口边仰坡的防护具有参考意义。
Due to the limitation of the terrain and position in the entrance section of highway tunnels,the high steep slope is inevitable in engineering.The construction of tunnel entrance would change the balance of the original mountain,easy to induce the geological disasters such as landslide and collapse of the high steep slope of the tunnel entrance.Based on the project of Fenghuangshan Tunnel,this paper carries out the stability analysis and safety evaluation of the entrance and exit slopes of its left and right lines,which provides technical support for the safety of tunnel engineering,and reference for the protection of similar tunnel entrance slope.
