摘　　要：对预应力锚杆格构梁加固边坡的作用机理、工作过程及受力阶段进行了阐述,同时分析了预应力锚杆格构梁的节点锚固力分配问题,并对预应力锚杆格构梁的地基计算模型进行了归纳。在格构梁的设计计算中应尽量考虑梁与土体的共同变形,选择符合实际情况的地基模型,使计算结果更加接近于格构梁的真实受力情况。This paper presents the action mechanism, working process and stressing stage of prestressed rockbolt lattice beam used to strengthen the slope, analyzes the distribution of node anchoring force of the lattice beam, and summarizes the foundation computation model of the prestressed rockboh lattice beam. Full consideration shall be given to the common deformation of the lattice beam and the soil in design calculation, and foundation model in line with the actual situation shall be selected so as to make the computation results more close to the real condition of the stressed lattice beam.
