摘　　要：现阶段,光伏项目中的光伏支架大多是小跨度的刚性结构,这种支架跨度较小,基础较多,适用于地势较平整、坡度不大或者对结构跨度要求不高的地面光伏电站,对于一些地形复杂或者坡度较陡的山坡地形,受场地地形条件限制,传统的固定支架施工难度较大,并且由于阴影遮挡影响,很多场地不能充分使用,土地浪费严重;对于渔光互补项目,传统刚性支架基础较多,影响渔业养殖。为了解决上述不足,提出了一种用于光伏项目的柔性悬索支架结构,可跨越较大的河道、深沟,能够充分利用土地资源;另外,为了控制风荷载作用下结构变形,降低组件隐裂风险,分析了不同张拉控制条件下,结构的刚度、内力变化特征,提出了张拉控制方案。At this stage, most of the PV brackets in PV projects are small-span rigid structures, which have a small span and more foundations and are suitable for ground PV power plants with flatter terrain, less slope or less demanding multi-structure span. As for some terrain complex or hillside terrain with steep slope, the traditional fixed bracket construction is more difficult due to site terrain conditions. Furthermore, many sites cannot be fully used due to shadow shading influence and serious land waste. As for fishery-photovoltaic complementary projects, there are more traditional rigid bracket foundations, which affect fishery farming. In order to solve the above deficiencies, a flexible suspension bracket structure for photovoltaic projects is proposed, which can span larger rivers and deep ditches and can make full use of land resources. In addition, in order to control the structural deformation under wind load and reduce the risk of hidden cracking of components, the paper analyzes the stiffness and internal force change characteristics of the structure under different tension control conditions, and then proposes a tension control scheme.
