| 摘 要： | 复合地基上褥垫层的设计是桩体复合地基设计的关键技术 ,通过对桩土应力比与褥垫层厚度关系的理论推导分析 ,并采用在水泥土桩单桩复合地基载荷试验中设置不同厚度褥垫层的方法 ,得到了褥垫层作用下桩土应力比的分布规律 ,此分布规律与理论分析一致。该研究为复合地基褥垫层合理厚度的设置及复合地基优化设计提供了依据

| Abstract: | The design of cushions is a key to the design of a composite foundation.The theoretical formula of the relationship between the thickness of the cushions and the pile soil stress ratio is analysed.Several single pile loading tests of the cement soil pile composite foundations are conducted with the cushions of different thickness.The influence of the thickness of the cushions on the pile soil stress ratio is then studied.The research in this paper will provide a theoretical evidence for a suitable selection of the thickness of the cushion and an optimal design for the composite foundations. |
