摘　　要：高强不锈钢绞线网-渗透性聚合物砂浆加固技术是近年来兴起的新型加固工艺,具有耐火、耐腐蚀、耐老化等优点。针对该加固工艺,对4根钢筋混凝土矩形梁和1根对比梁进行了剪切破坏对比试验,并分析加固梁抗剪破坏机理,探讨加固方式、二次受力、持载程度等对抗剪加固性能的影响,以获得有指导意义的结论。Rehabilitation of RC members with stainless steel wire mesh and permeability polymer mortar is a new method of structural strengthening with the advantages of resistance to fire, corrosion and aging. Experiments are conducted to investigate the shear behavior of four strengthened RC rectangular beams and one comparative RC beam. The shear mechanism of strengthened beams is analyzed, and the influences of the strengthening manners, secondary load, and the degree of loading on the shear behavior of strengthened beams are discussed. And the correlative conclusions are gained.
