山地光伏大跨度双层索柔性支架研究分析OA

With the rapid development of the photovoltaic(PV)industry,flexible PV supports have gained widespread application in flat areas due to their superior adaptability to terrain,higher space utilization,and reduced land excavation compared to traditional fixed supports.However,flexible supports with large spans are less commonly applied in mountainous regions with complex terrain and undulating ground.To address the challenges associated with the application of large-span flexible supports in mountainous areas,the authors take a specific mountain PV project as an example,based on actual measured terrain data,a double-layer cable flexible support model with a horizontal span of 51 meters was established using finite element software,meeting the project requirement of a 2.5-meter clearance.By analyzing the cable deflection,cable stress,and support reactions of the flexible support system,the reliability and applicability of the large-span double-layer flexible support in complex mountainous terrain were validated.Additionally,measures and suggestions to ensure the stability of the support system during construction were proposed,which can serve as a reference for the design and construction of similar projects in the future.
