摘　　要：本文提出了张弦梁式、索拱式及索桁架式共计3种可用于近岸海(水)上的柔性光伏支架结构,并对其结构内力及变形进行了有限元模拟分析,给出了其结构计算方法,分析了结构性能及优缺点。在此基础上对单位面积光伏板对应的支架及基础结构工程量进行了对比分析。分析表明:索桁架式支架的上部结构用量最少,张弦梁式支架的下部结构用量最少。张弦梁式和索拱式上部结构需要的钢材较多,但其可实现预张力自平衡,对下部结构的水平承载力要求较低,更适合软土地基;而索桁架式结构对两端下部结构的水平承载力要求较高,更适合地质条件较好的区域。相关研究成果可为类似工程或结构提供参考和借鉴。Three flexible photovoltaic supports can be used for offshore works,including string beam,cable arch and cable truss structures.The internal force and deformation of the above structures were analyzed through finite element model,which led to the calculation methods,performances,merit and demerit of different structures.Furthermore,the number of supports and the amount of work for foundation structure corresponding to unit area of photovoltaic panel were analyzed,which showed that the superstructure of cable truss support required the least steel material,and the lower structure of string beam support required the least steel.In contrast,the superstructure of string beam and cable arch structures required more steel,but the pretension self balance could be achieved,which decreased the horizontal bearing capacity of the lower structure and applied to soft soil base.The cable truss structure required higher horizontal bearing capacity of the lower structure at both ends,was suitable for the area with good geological conditions.The relevant research results may serve as a reference for similar projects or structure.
