摘要
针对高陡边坡或地质和环境条件复杂的边坡,边坡土体的下滑力矩大于抗剪强度的下滑力矩,高陡边坡失稳问题,采取在高陡边坡下部顺坡斜向打入钢管抗滑桩,斜向钢管抗滑桩的下部设置卡盘式钢筋混凝土悬臂板梁,增强斜向钢管抗滑桩抵抗力矩,抵御高陡边坡坡脚弧滑。同时在钢管抗滑桩之间土坡面采用喷射混凝土护面及反滤渗透排水管等四项技术措施联合工作形成一个支护体系,共同承受边坡土体和土中水产生的水平压力,有效避免高陡边坡坡脚弧滑,保持高陡边坡稳定。
Under the condition of high and steep slope or complex geological and environmental slope, thesoil slope slide torque is greater than the shear strength of slide torque. According to that high and steep slope instability problem, measures are taken to strengthen resistance torque of steel pipe pile such as： piling steel pipe anti-slide pile into the lower steep slope, and arranging a chuck type reinforced concrete cantilever plate beam on the lower part of it. A supporting system are formed by taking four technical measures such as jetting concrete surface and laying reverse osmotic drainage pipes on soil surface between the steel pipe pile and so on, which effectively avoids high and steep slope foot arc slide andkeeps the slope stability.
