应用于强腐蚀性临海滩涂的光伏支架桩基的优化设计研究OA

In view of the characteristics of coastal mudflat,such as strong corrosion,thick soft soil layer,high water level,and harsh climate,this paper based on an actual PV power generation project located in the strongly corrosive coastal mudflat,first introduced the background and geological conditions of the project,then studied the impact of pile-soil interaction effect and wind load occlusion effect on the internal force of the pile foundation,and compared the economy of traditional PHC pipe piles and PHC bamboo joint pile(hereinafter referred to as"bamboo joint"),finally summarized the common anti-corrosion measures and design points of the selected PHC pipe piles.The research results show that:1)When designing the pile foundation for PV bracket in the coastal mudflat area,the pile foundation internal force increase effect caused by the pile-soil interaction must be considered to ensure the safety and reliability of the pile foundation design scheme.2)After considering the wind load occlusion effect,the internal force of the pile foundation will be reduced,which can lower the total cost of the project's pile foundation.3)Compared to bamboo joint pile,traditional PHC pipe piles have advantages in quality control,construction difficulty,and economy.4)The design process of pile foundation should pay attention to requirements such as typhoon resistance and anti-corrosion,reduce the number of joints of PHC pipe pile,and strengthen joint anti-corrosion treatment.The research results have important reference value for the construction of PV power generation projects in the strongly corrosive coastal mudflat.
