摘　　要：在公路边坡工程的防护设计中,锚杆的锚固设计是较常用的防护形式,而在锚杆的设计中锚固角是一个很关键的参数,关系到整个锚固边坡工程的稳定性和经济性.该文通过综合分析锚杆的锚固角对锚固边坡工程的安全性和经济性两方面的影响,确定锚杆最佳锚固角的表达式,并通过PLAXIS 2D数值模拟的方法验证最佳锚固角的实用性.数值模拟结果显示锚杆的最佳锚固角度在40°时最为适宜,边坡的安全系数基本达到最大值,锚杆的锚固效果最好,边坡的稳定性也最为可靠.In the field of highway slope engineering,the anchoring design of anchor rods represents a common and effective form of protection.As a pivotal component in the engineering of anchor rods,the anchoring angle exerts a significant influence on the stability and economic viability of the comprehensive anchoring slope engineering system.This article presents a comprehensive analysis of the impact of the anchoring angle of anchor rods on the safety and economy of anchoring slope engineering.It determines the optimal anchoring angle for anchor rods and verifies the practicality of this angle through PLAXIS 2D numerical simulation.The results of the numerical simulation demonstrate that the optimal anchoring angle of the anchor rod is 40°,which results in a slope safety factor that is essentially at its maximum value.The optimal anchoring effect is achieved with the anchor rod,which also offers the greatest stability to the slope.
