沙漠地区光伏支架基础选型研究
Different Foundation Selection of Photovoltaic Support in Desert Area
当前国家大力推广在沙漠、戈壁、荒漠地区建设大型光伏基地,但由于沙漠风积沙具有级配差、质地松散、流动性大等特点,对光伏支架基础稳定性及耐久性的影响与其他场地相比有较大的区别。因此,研究沙漠地区光伏支架基础的合理选型尤为重要。为了探究适合在沙漠地区使用的光伏支架基础型式,在总结大量已有文献的基础上,采用层次分析法从可靠性、效率性、环保性、经济性、耐久性等方面对5种常见的光伏支架基础进行对比,研究表明预应力管桩的权重最大为0.221,螺旋钢管桩的权重0.203,混凝土灌注桩的权重为0.068,型钢桩的权重为0.110,钢筋混凝土条形基础的权重为0.042。此外,通过MATLAB数值模拟研究发现,预应力管桩的25 a累积腐蚀深度和桩顶水平位移最小,性能最优,推荐采用预应力管桩作为沙漠地区光伏支架基础。
Currently, China is vigorously promoting the construction of large-scale photovoltaic bases in desert and Gobi regions. However, due to the characteristics of desert wind-accumulated sand, such as poor gradation, loose texture, and high fluidity, its impact on the stability and durability of photovoltaic support foundations is significantly different from that of other sites. Therefore, it is particularly important to study the reasonable selection of photovoltaic support foundation types in desert areas. To explore suitable photovoltaic support foundation types for use in desert areas, this paper summarized a large number of existing literature, and employed the Analytic Hierarchy Process (AHP) to compare five common photovoltaic support foundations based on reliability, efficiency, environmental protection, economy, and durability. The study showed that the weight of the stress pile was 0.221, the weight of the spiral steel pipe pile was 0.203, the weight of the concrete cast-in-situ pile was 0.068, the weight of the H-shaped steel pile was 0.110, and the weight of the reinforced concrete strip foundation was 0.042. In addition, numerical simulations using MATLAB found that the 25-year accumulated corrosion depth and pile head horizontal displacement of prestressed pipe piles were the smallest, indicating the best performance. It is recommended to use prestressed piles as the photovoltaic support foundation in desert areas.
