摘要： 在季节性冻土地区建设光伏电站时，光伏支架基础易受冻胀影响不均匀抬升，造成上部支架及组件变形破坏。
以辽宁省阜新市一光伏电站为例，对冻土地区光伏支架基础选型、设计及优化进行了探究，提出了减小桩身切向冻胀力
的措施，明显减少了工程投资，保证了工程质量。

Abstract: When photovoltaic power stations are constructed in seasonal frozen regions, the foundations of photovoltaic bracket
are easily affected by frost heave and unevenly lifted, resulting in deformation and damage of the upper brackets and components.
Taking a photovoltaic power station in Fuxin City, Liaoning Province as an example, this paper explored the selection, design and
optimization of photovoltaic bracket foundations in seasonal frozen areas, and proposed the measures to reduce the tangential frost
heave force of the pile, which significantly reduced engineering investment and ensured engineering quality.

Key words: seasonal frozen soil; photovoltaic bracket; PHC precast tubular pile; replacement method
