沙漠地区光伏支架基础选型研究
Different Foundation Selection of Photovoltaic Support in Desert Area
摘要
Abstract
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 suit-able 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,effi-ciency,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.关键词
