摘　　要：随着城市开发向滨海软土场地发展,PHC管桩+无梁板地基处理以其质量可靠、施工快速、效果优良的优点正广泛得到应用。本研究以宁德市某工业园配套厂房项目PHC管桩结合无梁板地基处理为例,通过有限元数值模拟分析了场地地基土的应力应变状态,针对其特性提出了相应工程设计措施,为后期类似软土场地地基处理工程设计提供了参考及依据。With the development of urban development to coastal soft soil sites,PHC pipe pile combined with beamless slab ground treatment is being widely used for its advantages of reliable quality,fast construction and excellent effect.In this study,taking the PHC pipe pile combined with beamless slab ground treatment of an industrial production base project in Ningde City as an example,the stress and strain state of the site ground soil was analyzed through finite element numerical simulation,and corresponding engineering design measures were put forward according to its characteristics.This research can provide reference and basis for another similar soft soil site foundation treatment engineering designs.
