摘　　要：对高强钢绞线网-聚合物砂浆加固钢筋混凝土柱进行大偏压和小偏压的试验研究与理论分析.考虑不同的混凝土强度等级、偏心距和钢绞线含量等设计参数,对比分析了各种因素影响下18根钢筋混凝土柱的破坏形态、承载力和变形性能等.在此基础上,归纳提出高强钢绞线网-聚合物砂浆加固钢筋混凝土柱的承载力计算公式,计算值与实验值吻合良好.This paper presents an experimental study and theoretical analysis of the reinforced concrete（RC） column strengthened by composite cover of high-strength wire cable mesh and polymer mortar under eccentric compression loading with both large and small eccentricities.Take into account the influences of the design variables,including the strength grade of concrete,eccentric distance and content of wire cable,a comparative research has been carried out on the failure pattern,bearing capacity and deformation performance of 18 RC columns.Subsequently,a fitting formula of bearing capacity has been presented for RC column strengthened by composite cover of high-strength wire cable mesh and polymer mortar,which shows a good agreement with experimental data.
