根据金山路堑的工程地质条件 ,利用极限平衡理论对京沪高速公路金山路堑K74 + 4 50～K74+ 6 30段边坡作出稳定性评价 .讨论用锚杆、抗滑桩、锚索等方法加固该边坡的可能性 .结合该公路的等级 ,并考虑到施工的方便及国内外岩质边坡加固的经验 ,对这三种加固边坡的方法作了分析比较 ,确定采用预应力锚索加固本边坡的方案
According to the engineering geological conditions of Jinshan cutting, this paper makes use of the theory of limit equilibrium to evaluate the stability of K74 + 4 50 ~ K74 + 6 30 slope of Jinshan cutting of Beijing-Shanghai Expressway.It is discussed that using anchor, anti-slide piles, The possibility of the slope.According to the grade of the highway, taking into account the construction convenience and the experience of rock slope reinforcement at home and abroad, the three methods of reinforcement slope are analyzed and compared to determine the use of prestressed anchor reinforcement The slope of the program
