摘要
Abstract
As a representative of new energy utilization methods,PV power generation technology has become the top choice for the development of new energy.Section-steel piles for PV brackets,due to their strong penetration and ease of transportation and construction,are extensively used in desert PV power stations.Through 3D finite element numerical simulation analysis,this paper explored the bearing characteristics and force mechanism of section-steel piles for desert PV brackets,as well as the impact and regularity of parameter variations on the bearing performance of the section-steel piles.The research results show that the cross-sectional shape of the section-steel pile is the key factor determining its bearing performance,and its bearing performance is positively correlated with the cross-sectional area and the length of the pile.The wind load in the desert area significantly affects the bearing characteristics of the section-steel piles,not only altering their bearing performance and deformation but also progressively reducing their bearing performance and increasing settlement deformation with the increase in load cycle counts.关键词
