摘　　要：通过对9根圆柱单调加载的对比试验,研究了钢筋网高性能水泥复合砂浆加固混凝土圆柱的轴压性能。在试验研究和理论分析的基础上,揭示了此种加固薄层使柱各项性能得以改善或增强的作用机理,建立了加固混凝土圆柱的承载力计算模型与计算公式。The axially college behavior of RC strengthening round columns using high performance composite cement mortar reinforced with mesh reinforcements was studied by monotonic loading comparison experiment of nine round columns. Based on the experimental research and theory analysis, the acting mechanism of the CMMR laminates improving or increasing various performances of strengthening columns was exposed, the simple and suitable model and formulas were concluded for calculating the load-bearing capacity of the strengthening round columns.
