［摘要］采用玄武巖纖維編織網對鋼筋混凝土圓柱體進行加固，分別考察了環(huán)氧樹脂、高延性水泥基復合材料(ECC)兩種界面粘結劑復合玄武巖纖維編織網及ECC不同復合工藝對鋼筋混凝土圓柱體軸壓性能的影響。結果表明：玄武巖纖維編織網通過與上述兩種界面粘結劑復合均能有效地提高鋼筋混凝土圓柱體的極限承載力，提高幅度為40-2%～62%，對圓柱體表面噴射ECC復合玄武巖編織網對鋼筋混凝土圓柱體極限承載力提高更為顯著，提高幅度達61-7%。最后，通過對兩種粘結劑復合玄武巖編織網加固鋼筋混凝土圓體體的極限承載力進行計算，提出“極限強度模型”，通過對此模型采用求極值的方式可以有效地對鋼筋混凝土圓柱體的極限承載力及其受力過程進行預測。

Abstract:The reinforced concrete cylinders were reinforced by basalt fiber braided mesh. The effects of two interfacial binders of epoxy resin and high ductile cement matrix composites (ECC) for composite basalt fiber braided mesh on axial compression performance of reinforced concrete cylinder were studied. The effects of different ECC composite technics on axial compression performance of reinforced concrete cylinder were investigated. The results show that the basaltic fiber braided mesh with the combination of the two kinds of interfacial binders can effectively improve the ultimate bearing capacity of reinforced concrete cylinders by 40-2%～62%. The ECC composite basalt braided mesh sprayed on the cylinder surface has more significant improvement in the ultimate bearing capacity of reinforced concrete cylinders by 61-7%. Finally, by calculating the ultimate bearing capacities of reinforced concrete cylinder reinforced by composite basalt braided mesh with two kinds of binders, the “ultimate strength model” was proposed. By using the method of calculating the extreme value for the model, ultimate bearing capacity of the reinforced concrete cylinder and its stress process could be predicted.
Keywords:basalt fiber braided mesh; interface binder; reinforced concrete; axial compression property; ultimate strength model
