柔性光伏支架高悬臂桩基的计算研究OA

Flexible PV brackets are widely used in scenarios such as fishery-PV complementarity,sewage treatment plants,agriculture-PV complementarity,and pasture-PV complementarity,in such scenarios,flexible PV brackets often use high cantilever pile foundations.This paper takes the high cantilever pile foundation as the research object,based on the relevant specifications for building pile foundations and PV brackets,and systematically explores the calculation method of the horizontal bearing capacity of such pile foundations under bending moment through formula derivation,within the set numerical research interval,numerical analysis is used to quantify the influence of bending moment on the horizontal bearing capacity.Then,a systematic analysis is conducted on the numerical relationship between the horizontal bearing capacity calculation of the pile foundation and the pile(column)top horizontal displacement calculation and overturning calculation.The research results show that:1)Within the numerical research interval set in this paper,the bending moment generated by the cantilever section has a strong weakening effect on the horizontal bearing capacity of the high cantilever pile foundation,when calculating the horizontal bearing capacity,of the pile foundation the derived formula for calculating the horizontal bearing capacity considering the action of bending moment should be used.2)According to the requirements of relevant specifications,the horizontal bearing capacity calculation considering bending moment can replace the pile(column)top horizontal displacement calculation and overturning calculation under the given soil mechanics parameters,without risk of exceeding the limit,The research results can provide theoretical references for the design of high cantilever pile foundations for flexible PV brackets.
