Research on Nearshore Flexible Photovoltaic Support
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.
