摘　　要：为了进一步研究压力型锚索的锚固机理,以集中力作用于半无限体的Boussinesq问题解为基础,推导出圆形均布荷载作用下Boussinesq的近似解来研究压力型锚索注浆体受到的压应力和接触面上的剪应力,并分析了承压板半径、锚索孔半径及预应力荷载大小对压应力和剪应力的影响。研究结果进一步丰富了压力型锚索的锚固机理,可为实际工程中压力型锚索的应用提供理论参考。In order to further study the anchoring mechanism of cable, the expression of normal stress of grouting and shear stress in prestressed cables were derived on the basis of the Boussinesq approximate solution and the influences of bearing plate radius, radius and prestressing force on pressure stress and shearing strength were analyzed. The results can further enrich the anchoring mechanism of pressure-type cables and can provides the theoretical reference for the engineering application of pressure-type cables.
