摘　　要：研究分析了钢筋混凝土电杆产生纵向裂缝的机理，并采用钢纤维来抑制或限制电杆纵向裂缝的发生和发展；进行了电杆纵向裂缝控制措施的试验研究；还对钢筋混凝土和钢纤维混凝土电杆试件进行了抗冻性和抗腐蚀性的对比试验。The mechanism of longitudinal crack taking place and propagating is analyzed for reinforced concrete poles. Longitudinal crack of the poles is restrained by using steel fiber in reinforced concrete poles. The comparing experiments between reinforced concrete poles and steel fiber reinforced concrete poles on the crack restriction, freezing resistance, corrosion resistance are carried out. From the test results it is found that the behavior of cracking strength, freezing resistance, corrosion resistance of steel fiber reinforced concrete poles is better than that of reinforced concrete poles. The test results can be used in practical engineering.
