摘　　要：随着中国公路建设的高速发展,边坡稳定问题日渐突出,对现状边坡支护结构失效后的边坡加固设计需求日益增加。该文通过介绍边坡加固工程的应用现状,描述格构式锚杆护坡的优点及不足,分析格构梁及锚杆失效的原因,结合工程实例,详细论述了在原有格构式锚杆护坡失效后的五种边坡二次加固措施,其中的锚固措施不仅安全有效,对边坡扰动较小,且施工相对容易,可为日后边坡加固设计提供参考。With the rapid development of highway construction in China,the problem of slope stability has been increasingly prominent,which leads to an everincreasing demand of slope reinforcement design after the failure of the existing anchor lattice truss.By introducing the application status of slope reinforcement measures,the advantages and disadvantages of lattice truss rockbolts as well as failure causes are described,combined with an engineering case,this paper gives a detailed description of five secondary slope reinforcement measures after the failure of the existing lattice truss rockbolts.The anchoring measure is not only effective,but also has a small disturbance for the slope and convenient construction,which provides reference for slope reinforcement design.
