摘　　要：虽然锚索框架是加固边坡非常有效的支挡结构型式,然而其计算模型以及相应的计算理论仍不完善,在某些方面并不能反映其真实的受力过程和工作状态;坡体与锚索框架梁是一个相互作用、受力不断调整的过程,而目前对锚索框架梁的研究都是将锚索框架梁分成为预应力锚索和框架梁分别单独进行分析,缺乏对锚索框架梁整体的分析总结;通过对预应力锚索框架梁的施工过程和作用机理的分析,探讨了预应力锚索框架梁计算模型的两个重要环节,并建立了一个更加合理、真实的锚索框架梁变形协调方程。Although the prestressed anchor with frame beam is a very effective supporting structure in reinforcing slopes,the computational model and corresponding theory of calculation are still not perfected,which cannot reflect the true working state and real process of force. The slope and prestressed anchor frame beam interact with each other and the force is continually readjusted,but at present the research of prestressed anchor frame beam are divided into prestressed anchor and frame beam separately to analyze,which is lack of overall summary analysis on it. Based on the analysis on construction process and mechanisms,two important aspects of the computational model on prestressed anchor frame beam were discussed and a more reasonable and real equations of coordinated deformation was established.
