摘要: 陡倾岩质边坡由于受工程地质条件、水文地质条件及施工扰动的影响,在隧道洞口施工过程中极易产生滑坡。综合武罐高速公路马桑坝隧道洞口滑坡的形成特点及工程地质条件,采用有限差分软件FLAC(3D)对该隧道洞口的开挖与爆破施工、边坡失稳及加固过程进行了数值模拟和分析,并提出了提出针对性治理方案,得到较好效果。Abstract: Landslide is quite regular in steep rock slope due to the engineering geological condition, hydro-geologicalcircumstances, and some human activities, For the landslide formation feature, the geological condition and the hydro geological condition of Masangba tunnel of Wudu-Guanzigou Expressway, several kinds of working conditions of this land-slide is analyzed by using flac3d. Finally, the reinforcement scheme is proposed and proved to be effective.
