摘　　要：为既克服纤维复合材料加固混凝土柱耐久性和耐火性较差且成本太高的缺点，又克服混凝土加大截面加固法需支模等工续导致施工复杂的缺点，提出用钢丝网水泥砂浆加固混凝土圆柱的思路。进行钢丝网砂浆加固和钢筋网砂浆加固柱抗轴压对比试验研究，并探讨工作机理。结果表明，与钢筋网加固柱相比，钢丝网加固柱更易于施工，试件延性更大，相同配箍率条件下承载力更高。In order to both overcome the shortcomings of low durability and poor fire-resistance as well as high cost of FRP strengthening concrete column, and simplify the complex strengthening procedures of enlarging column section with RC（such as formwork）, a thought to strengthen circular columns with ferrocement was proposed. A comparison experimental study between ferrocement strengthening and steel bar-mesh strengthening columns under axial load was carried out. The working mechanism was discussed. The results showed that, compared with steel bar-mesh strengthening, the ferrocement strengthening was easier to perform, led to a higher ductility, and obtained a higher load carrying capacity under a same reinforcement ratio.
