Through the establishment of a highway slope model, using the limit equilibrium method, to study the impact of mortar anchor parameter variations on the slope, the study results show that: (1 ) when the bolt arrangement unchanged, the increase in the length of the bolt, the slopethe safety factor appears increases first and then basically stable trend. (2) When bolt length and anchoring force keeps constant, with the bolt inclination increases , the slope safety factor presents first increases first and then decreases. (3 ) If the bolt length keeps as the same, when bolt Tension increases, the slope safety factor presents increase first and then basically stable trend. The research results provide a theoretical basis for engineering design similar to the slope stability.%通过建立某公路边坡模型,采用极限平衡方法,研究锚杆参数变化对边坡的影响.研究结果表明:(1)当锚杆布置方式不变时,锚杆长度的增加,边坡安全系数呈现先增大后基本稳定的趋势.(2)当锚杆长度与锚固力不变,随着锚杆倾角的增大,边坡安全系数呈现先增大后减小的趋势.(3)当锚杆长度不变,锚杆张拉力的增加,边坡安全系数呈现先增大后基本稳定的趋势.研究结果为类似边坡稳定的工程设计提供理论依据.
