摘要(Abstract)：
钢筋水泥杆是电网中的重要构建,其安全性关系到输电线路的正常运行,因此提高对钢筋水泥杆的检测水平显得尤为必要。试验研究了不同保载时间对不同规格的锥形钢筋水泥杆力学性能的影响。研究表明,在相同条件下,随着荷载保载时间的延长,钢筋水泥电杆挠度呈先增加后稳定的趋势,同时研究发现保载时间对电杆裂缝宽度及条数有一定影响。最后,结合试验数据分析了挠度随保载时间变化的原因,为更好地检测钢筋水泥杆提供了科研依据,同时也为钢筋水泥杆检测技术的改进提出了一些建议。
Reinforced concrete poles are important component parts of power grid and their safety is related to the normal operation of transmission lines. Therefore, it is particularly necessary to improve the detection level of reinforced concrete poles. The effect of different loading time on the mechanical properties of conical reinforced cement poles with different specifications was studied. The results show that with the extension of load holding time the deflection of reinforced concrete pole increases first and then stabilizes under the same conditions. At the same time, it is found that the holding time has certain influence on the crack width and the number of poles. Finally, by combining with the test data, the paper analyzes the reason of deflection with the holding time change, which provides scientific basis for better detection of reinforced concrete poles; besides, it also puts forward some suggestions for improving the detection technology of reinforced cement poles.
