针对高回填土排土场建设光伏电站后的沉降变形难题,基于山西平朔矿区排土场农光互补光伏发电项目,分析沉降变形对光伏支架及基础的影响,并结合场地回填土情况,对光伏支架及基础选型、经济性等方面进行了研究分析,为高回填土排土场光伏支架及基础设计提供了解决方案。技术经济比选结果表明:高回填土排土场建设光伏电站,光伏支架宜采用固定光伏支架,光伏阵列宜采用短阵列,根据回填的时间长短选择光伏支架基础型式,并注重光伏电站建成后的变形观测。

Aiming at the settlement and deformation after building a photovoltaic power station in high backfill soil, based on the agricultural-photovoltaic complementary photovoltaic power generation project in Pingshuo mine area, Shanxi Province, the impact of settlement and deformation on photovoltaic supports and foundations was analyzed. Combining with the backfill soil situation of the site, the selection and economy of photovoltaic supports and foundations were studied, and a solution was provided for the design of photovoltaic supports and foundations on high backfill soil. According to the technical and economic comparison, the construction of photovoltaic power station in high backfill soil is suitable for fixed photovoltaic support, photovoltaic array is suitable for short array. The type of photovoltaic support foundation was selected according to the length of time of backfill. And it was emphasized that, the deformation of photovoltaic power station after completion should be closely monitored.
