RESEARCH ON CURRENT STATUS OF PV BRACKET FOUNDATION AND ITS STRUCTURAL OPTIMIZATION UNDER SAND AND GRAVEL GEOLOGY
摘要
Abstract
This paper analyzes 120 papers on PV bracket foundations in China using scientometrics,explores the annual publication trends and keywords co-occurrence,and investigates and analyzes the research status and trends of PV bracket foundations in China.Then,an in-depth study is conducted on the types,advantages,and disadvantages of PV bracket foundations,with a focus on the problems encountered in the application of PV bracket foundations in sandy and gravel geological environ-ments in northwest desert region of China,and structural optimization suggestions are proposed.The research results show that:1)From the perspective of the annual publication trends and keywords co-occurrence,the number of publications on PV bracket foundations is mainly affected by policies,and under the influence of intelligent PV and energy storage policies,the number of publications shows an increasing trend from 2021 to 2023.Foundation,pile foundation,PV bracket foundation and others are high-frequency keywords in this field on CNKI.2)Various types of PV bracket foun-dations exhibit respective advantages and disadvantages in application.When actual selecting,it is necessary to consider the actual situation of the project,taking into account the structural types and load characteristics of PV bracket foundation,soil properties and groundwater conditions,feasibility of construction technology,construction site conditions and seasons,economic indicators,environmental protection requirements,construction period,and other aspects for comprehensive analysis.3)The main problems faced by PV bracket foundations in the sand and gravel geological environment of the northwest desert region include foundation stability under wind and sand condi-tions,long-term operation reliability assessment,and environmentally friendly foundation design.The optimization of its structure can be achieved by selecting appropriate type and size of the founda-tion.And the stability and bearing capacity of the foundation can be enhanced by injecting grout into the sand and gravel geology,and the foundation conditions can be improved by adding auxiliary facilities such as anti spray belts and dewatering wells,to enhance the stability of the foundation.The research provides theoretical basis and practical guidance for the selection and structural optimization of PV bracket foundations.关键词
