| 摘 要： | 以岫岩小虎岭工程边坡为例,为了评价和研究含破碎带的岩质高边坡稳定性及抗滑桩加固效果。通过现场大型直剪试验和室内试验获得计算参数,基于数值模拟采用有限元强度折减法分析其稳定性并获得安全系数。结果表明破碎带是影响边坡稳定的主要原因,边坡塑性贯通区与破碎带形状一致;自然状态下安全系数为1.01,属欠稳定坡,采用抗滑桩加固后安全系数提高至1.72;安全系数在一定范围内随破碎带土体的c、φ值的增大而增大。

| Abstract: | The stability of high rock slope which contained fracture zone and the reinforcement effect of anti-slide pile were evaluated and studied based on a practical case of an engineering slope in the area of Xiuyan Xiaohuling.The calculated parameters were obtained via large direct shear strength tests in the local field and laboratory tests,at the same time,the stability and safety factor were analyzed and obtained through numerical analysis based on Strength Reduction FEM. Result indicates that the fracture zone is the key reason to the influence of the slope stability,the area of max shear strain is similar to fracture zone''s shape in slope,and the slope belongs to unstable slope in nature status because of the safety factor was 1.01,the safety factor was increased to 1.72 after using anti-slide pile,safety factor of slope along with the andvalue of fracture zone increases in a certain range. |
