劲性桩复合地基在工程中应用

Engineering Application of Composite Ground with Rigid Columns

对于工程建设中遇到的厚层素填土,应选择合适的地基处理方案。鉴于单一桩型的局限性,将常用的散体桩(S桩)、水泥土类桩(M桩)和混凝土桩(C桩)中的两种或三种进行复合,形成互补增强的劲性复合桩型,结合了各种桩型的优点,充分体现出优越的经济技术效益。

It is a challenge to select the proper ground improvement techniques for the construction that involves thick fill materials.This paper presents a project located in Huaian,Jiangsu Province which successfully utilized composite ground with rigid column（RC）foundation to improve the ground conditions for three structures.The composite ground with rigid column（RC）foundation was proven to be technically sound and economically effective.
