摘　　要：为研究柔性光伏支架桩基在局部淤泥质土较厚区域的水平承载力和稳定性,文中通过江苏某渔光互补发电项目,采用规范公式进行了相关验算,并对水平力作用下桩土共同作用进行有限元分析验证。结果表明,柔性光伏支架桩基设计规范方法与有限元结果较为相符,桩基的水平承载力和稳定性满足规范要求。总结分析锚杆抗拔承载力的计算方法和深厚淤泥质土区域光伏锚杆的加强措施。相关结论可为同类项目设计提供参考。This paper studies the horizontal bearing capacity and stability of flexible photovoltaic bracket pile founda⁃tion in areas with thick local muddy soil.Taking a photovoltaic complementary power generation project as the case,relevant calculations are verified with standard formulas,and effectiveness of pile and soil under horizontal force are analyzed using finite element method.The results show that the design specification method for flexible photovoltaic bracket pile foundation is in good agreement with the finite element results,and the horizontal bearing capacity and stability of the pile foundation meet the requirements of the specification.Finally,the calculation method for the pull-out bearing capacity of anchor rods and the strengthening measures for photovoltaic anchor rods in deep muddy soil areas were introduced.The relevant conclusions may provide the reference for the design of similar projects.
