Therefore, this paper aims to investigate the application of bionics principles to propose a novel type of photovoltaic bracket pile foundation designed to meet diverse bearing capacity requirements, specifically suited for desert gravel areas: the photovoltaic bracket serpentine pile foundation.
The traditional photovoltaic bracket pile foundation, while possessing high compressive strength, is susceptible to uplift forces under wind loading, leading to a host of issues 15.
Moreover, Shalabi et al. 24 developed a numerical model for the joint loading of drilled piles and the bearing platforms above them, observing that under pressure loading, the contribution of pile end bearing capacity to total foundation bearing capacity increases with the rise of the length-to-diameter ratio of grouted piles.
As the primary load-bearing element of the photovoltaic power generation system, the PV racking pile foundation not only supports the system's own weight and external loads, but also constitutes a significant portion of the total construction cost due to the extensive quantity used 10, 11.
