摘　　要：为了研究锚杆弹性模量对赣南某高速公路高边坡稳定性的影响,采用数值模拟方法,研究了锚杆弹性模量对边坡最大水平位移、锚杆最大轴力、锚杆轴力分布和边坡安全系数的影响。结果表明,随着锚杆弹性模量的增加,边坡的最大水平位移呈现逐渐减小的趋势,边坡的安全系数初期随之增大,而后不再随弹性模量的增加而提升;锚杆的最大轴力随其弹性模量的增大而增大,且锚杆轴力的分布变得更加不均匀,可能对整体边坡的稳定性产生不利影响。研究结果可为高边坡锚杆选型和设计提供理论支撑。To investigate the impact of the anchor bolt elastic modulus on the stability of a high slope along a highway in southern Jiangxi,a numerical simulation was employed to study its effects on the maximum horizontal displacement of the slope,the maximum axial force of the anchor bolt,the distribution of axial force within the anchor bolts,and the factor of safety.The results indicate that as the elastic modulus of the anchor bolt increases,the maximum horizontal displacement of the slope exhibits a gradual decrease,while the factor of safety initially rises but subsequently plateaus,no longer increasing with further increments in elastic modulus.Additionally,the maximum axial force of the anchor bolt increases with its elastic modulus,and the distribution of axial force becomes more uneven,potentially adversely affecting the overall slope stability.These findings provide theoretical support for the selection and design of anchor bolts for high slopes.
