【摘要】 针对复杂山地地形场景下光伏支架布置的难题,提出了一种新型单层索系柔性光伏支架结构体系。该支架采用双立柱-支撑的中部支承结构和全铰接节点设计,以灵活适应地形起伏,且通过设置横向连接系和地锚系统增强整体稳定性与抗风能力。通过分析承重索及垂直索方向的地形坡度差异,探究不同起伏地形下承重索折角与支架结构受力的对应关系,明确坡度变化对索力的影响机理。采用有限元软件对结构进行动力响应分析,探究结构不同跨的跨中位移特征值,并与现行规范限值进行比对。分析结果表明,该体系能够有效提升复杂地形条件下支架的适应性,显著降低实施难度,为山地光伏应用提供了可行的实施方案。更多还原

【Abstract】 To address the challenges of photovoltaic(PV) support arrangement in complex mountainous terrain scenarios,this study proposes a novel single-layer cable system flexible PV support structure. The structural system incorporates a double-column support structure at the mid-span and fully hinged joint design to enhance terrain adaptability, while lateral bracing systems and ground anchor systems are implemented to improve overall stability and wind resistance.Through systematic analysis of terrain slope variations along the load-carrying cable direction and transverse cable direction, a correlation framework between cable folding angles and structural mechanical responses under diverse topographic conditions was explored, clarifying the influence mechanisms of slope variations on cable forces. The dynamic response of the structure is analyzed by finite element software to explore the characteristic values of mid-span displacements for different spans of the structure and compare them with the current code limits. It has been demonstrated that this proposed system effectively improves adaptability to complex terrains, reduces construction challenges, and provides a feasible implementation scheme for mountainous PV engineering applications.更多还原
