摘　　要：针对光伏支架在软塑/流塑软弱土场地应用时存在的一些问题,提出一种半预制轻型光伏支架基础形式,旨在克服常规基础因受场地限制不适用,或施工难度大、建设成本较高的问题。通过沉降计算分析,在满足软塑/流塑软弱土地基承载力及基础整体稳定性的前提下,该半预制轻型光伏支架基础可以实现安装支架基础上方设施后,不增加基础底面附加压力,从根本上解决了光伏电站建设后场地地基的后续沉降问题。In view of the problems existing in the application of PV brackets in soft plastic/flow plastic soft soil sites,this paper proposes a semi-prefabricated lightweight PV bracket foundation form,which aims to overcome the problems of inappropriate application of conventional foundations due to site constraints or difficult construction and high construction costs.On the premise of satisfying the bearing capacity of the soft plastic/flow plastic soft soil foundation and the overall stability of the foundation,it is found through settlement calculation that this semi-prefabricated lightweight PV bracket foundation can achieve the installation of facilities above the PV bracket foundation without increasing the additional stress on the foundation bottom,the problem of subsequent settlement of the foundation after construction of PV power stations is fundamentally solved.
