摘要: 变电站户外构支架的材质在早期采用的是钢筋混凝土结构,由于其结构特性受当年技术水平影响,且人为施工质量受限,导致钢筋混凝土经多年使用后,在构支架表层处出现开裂和剥落的腐蚀现象,严重影响变电站的正常操作和安全运行。近年来,纤维增强复合材料(简称FRP)在变电站构支架加固中得应用越来越多。本文针对目前关于湿热条件下FRP加固构支架基本力学性能和长期受力性能研究较少的问题,对其进行了专门研究并提出综合治理方案。

Abstract: Early transformer substation outdoor trusses are all structured in reinforced concrete. Du to the structure feature of the concrete, technical limit and construction quality in the old days, with years' operation, corrosion of craze and peeling wildly appears on the surface concrete of these trusses which seriously affects transformer substation's operation and safety. Lately years,more substation framework are rein forced by FRP. In this Paper, a range of tests about the durability of FRP strengthening structures with wet-condition have been accomplished, and a comprehensive control strategy have been obtained.
