辽宁中部环线纱帽山隧道洞口路堑边坡滑塌处理方案浅析

Brief Analysis on Treatment Scheme for Cutting Slope Collapse of Shamaoshan Tunnel Portal of Loop Line in Central Part of Liaoning

辽宁中部环线纱帽山隧道洞口部分路堑边坡连续出现水毁滑塌,在对现场进行调查、分析滑塌成因后,制定了两套处理方案,经论证,综合两套方案的优点,最终确定实施方案,对不稳定边坡进行处治,使治理后的边坡达到稳定状态。阐述了纱帽山隧道洞口路堑边坡滑塌的处理方案及施工工艺。

Water damage and collapse continuously exist in cutting slope of Shamaoshan tunnel portal of loop line in central part of Liaoning. After the investigation on the site and analysis on the reason of collapse, two sets of treatment schemes are established. Through the demonstration, implementation schemes are finally determined by integrating the merits of two sets of schemes, so as to make treatment for unstable slope and make the slope after treatment achieve the state of stability. The treatment schemes and construction technologies of cutting slope collapse of Shamaoshan tunnel portal are elaborated.
