摘要
光伏支架基础是地面光伏电站的重要结构,起承载支架及光伏组件自重及抵御风荷载、雪荷载及地震荷载等全部动荷载的作用。支架基础根据实际环境,选用不同的桩基,其中包括微型桩。微型桩的结构、承载机理与常规桩基不同,理论支撑尚不成立,对其承载能力的检测方法和评价依据,目前也无统一的技术规程,实践中多是参照或借鉴其他行业的技术规程,缺乏针对性、适用性和一致性。通过工程实践和相关技术分析比较,以促进地面光伏电站结构安全和岩土工程技术提升。
Photovoltaic supporting bracket foundation is an important structure of ground photovoltaic power station. It supports the weight of bracket and photovoltaic components, and bears all dynamic loads, such as wind load, snow load and earthquake load, etc. The supporting bracket foundation chooses different pile foundations, such as routine filling pile, precast concrete pile and micro- pile, according to different environmental, geomorphic, geological and hydrological conditions. There is not an official technical regulation for test and inspection of the bearing capacity of micro-hole filling pile, which often uses the technical regulations of other industries, lacking of accttracy, applicability and consistency. This paper introduced engineering practices and compared relevant technical regulations, to increase structural safety of ground photovoltaic power station and improve geotechnical engineering techniques.
