摘要
以牛首山地区边坡为研究对象,结合工程地质报告及勘察资料,采用基于极限平衡法的软件对牛首山某边坡稳定性进行分析评价,提出边坡局部加固以及整体治理措施。结果表明,不满足稳定要求的滑动面主要分布于边坡中部,建议布置锚拉抗滑桩、预应力锚索框架梁进行局部加固。计算得到加固后滑坡滑动带顶、底面上部岩体的稳定系数。分析表明滑动带顶、底面上部岩体在天然和暴雨工况下均处于稳定状态,验证采取的治理措施能有效提高滑坡的稳定性。
Taking the slope of Niushou Mountain area as the research object,combined with engineering geological report and survey data,the stability of a slope in Niushou Mountain is analyzed and evaluated by the software based on limit equilibrium method,and the local reinforcement measures and overall treatment of the slope are put forward.The results show that:these sliding surfaces are mainly distributed in the middle of the slope.The anchor anti-slide pile and lattice beam with pre-stressed cable are suggested to reinforce locally.The stability coefficients of rock mass at the top and bottom of the reinforced sliding zone are calculated.The analysis shows that under natural and rainstorm conditions,the rock masses above the top and bottom of the sliding belt are in a stable state.The treatment measures can effectively improve the stability of the landslide.
